Postponed jobs are registered with this API. Registered jobs
are invoked at `ruby-running-safe-point' as soon as possible.
This timing is completely same as finalizer timing.
There are two APIs:
* rb_postponed_job_register(flags, func, data): register a
postponed job with data. flags are reserved.
* rb_postponed_job_register_one(flags, func, data): same as
`rb_postponed_job_register', but only one `func' job is
registered (skip if `func' is already registered).
This change is mostly written by Aman Gupta (tmm1).

of IFUNC frame.
When `rb_binding_new_with_cfp()' is called, VM finds out the first
normal (has iseq) frame and create a binding object of this frame
and create Env objects. `ep's of related frames are updated
(`ep's point Env object managed spaces).
However, `ep' of skipped IFUNC frame was not updated and
old invalid `ep' was remained. It causes serious problems.
To solve this issue, permit IFUNC to create binding.
(Maybe there is no problem on it)

Move `trace_arg' from rb_tp_t::trace_arg to rb_thread_t::trace_arg.
`trace_arg' may changed by multiple threads.
rb_thread_t::trace_arg can represent rb_thread_t::trace_running
(null or non-null) and rb_thread_t::trace_running is removed.
After that, `rb_tp_t' is not needed to check tracing or not
(A running thread knows tracing or not). This is why I remove
tp_attr_check_active() and make new function get_trace_arg().
And this modification disable to work the following code:
TracePoint.trace{|tp|
Thread.new{p tp.event} # access `tp' from other threads.

- RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
default: 128KB (32bit CPU) or 256KB (64bit CPU).
- RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
creation. default: 512KB or 1024KB.
- RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
default: 64KB or 128KB.
- RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
creation. default: 256KB or 256KB.
This values are specified at launched timing. You can not change
these values at running time.
Environ variables are only *hints* because:
- They are aligned to 4KB.
- They have minimum values (depend on OSs).
- Machine stack settings are ignored by some OSs.
Default values especially fiber stack sizes are increased.
This change affect Fiber's behavior:
(1) You can run more complex program on a Fiber.
(2) You can not make many (thousands) Fibers because of
lack of address space (on 32bit CPU).
If (2) bothers you,
(a) Use 64bit CPU with big memory, or
(b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
You need to choose correct stack size carefully. These values
are completely rely on systems (OS/compiler and so on).

add a new otpimization and its macro `OPT_CALL_CFUNC_WITHOUT_FRAME'.
This optimization makes all cfunc method calls `frameless', which
is fster than ordinal cfunc method call.
If `frame' is needed (for example, it calls another method with
`rb_funcall()'), then build a frame. In other words, this
optimization delays frame building.
However, to delay the frame building, we need additional overheads:
(1) Store the last call information.
(2) Check the delayed frame buidling before the frame is needed.
(3) Overhead to build a delayed frame.
rb_thread_t::passed_ci is storage of delayed cfunc call information.
(1) is lightweight because it is only 1 assignment to `passed_ci'.
To achieve (2), we modify GET_THREAD() to check `passed_ci' every
time. It causes 10% overhead on my envrionment.
This optimization only works for cfunc methods which do not need
their `frame'.
After evaluation on my environment, this optimization does not
effective every time. Because of this evaluation results, this
optimization is disabled at default.

(rb_method_cfunc_t::func).
`invoker' is set at method definition timing.
With this change, the big `switch' (branch) in `call_cfunc()'
is no longer needed.
However, the performance benefit is only a bit.
* vm_core.h (rb_call_info_t::aux::func): add a new field to store
cfunc body function pointer.

This technique simplifies parameter passings at related
function calls (~10% speedups for simple mehtod invocation at

`rb_call_info_t' also has new function pointer variable `call'.
This `call' variable enables to customize method (block)

(1) add rb_hook_list_t data structure which includes
hooks, events (flag) and `need_clean' flag.
If the last flag is true, then clean the hooks list.
In other words, deleted hooks are contained by `hooks'.
Cleanup process should run before traversing the list.
(2) Change check mechanism
See EXEC_EVENT_HOOK() in vm_core.h.
(3) Add `raw' hooks APIs
Normal hooks are guarded from exception by rb_protect().
However, this protection is overhead for too simple
functions which never cause exceptions. `raw' hooks
are executed without protection and faster.
Now, we only provide registration APIs. All `raw'
hooks are kicked under protection (same as normal hooks).

th->base_block is information for (a) parsing, (b) compiling
and (c) setting up the frame to execute the program passed by
`eval' method. For example, (1) parser need to know up-level
variables to detect it is variable or method without paren.
Befor (a), (b) and (c), VM set th->base_block by passed bindng
(or previous frame information). After execute (a), (b) and (c),
VM should clear th->base_block. However, if (a), (b) or (c)
raises an exception, then th->base_block is not cleared.
Problem is that the uncleared value th->balo_block is used for
irrelevant iseq compilation. It causes SEGV or critical error.
I tried to solve this problem: to clear them before exception,
but finally I found out that it is difficult to do it (Ruby
program can be run in many places).
Because of this background, I set th->base_block before
compiling iseq and restore it after compiling.
Basically, th->base_block is dirty hack (similar to global
variable) and this patch is also dirty.
* bootstraptest/test_eval.rb: add a test for above.

Before this commit:
`finish frame' was place holder which indicates that VM loop
needs to return function.
If a C method calls a Ruby methods (a method written by Ruby),
then VM loop will be (re-)invoked. When the Ruby method returns,
then also VM loop should be escaped. `finish frame' has only
one instruction `finish', which returns VM loop function.
VM loop function executes `finish' instruction, then VM loop
function returns itself.
With such mechanism, `leave' instruction (which returns one
frame from current scope) doesn't need to check that this `leave'
should also return from VM loop function.
Strictly, one branch can be removed from `leave' instructon.
Consideration:
However, pushing the `finish frame' needs costs because
it needs several memory accesses. The number of pushing
`finish frame' is greater than I had assumed. Of course,
pushing `finish frame' consumes additional control frame.
Moreover, recent processors has good branch prediction,
with which we can ignore such trivial checking.
After this commit:
Finally, I decide to remove `finish frame' and `finish'
instruction. Some parts of VM depend on `finish frame',
so the new frame flag VM_FRAME_FLAG_FINISH is introduced.
If this frame should escape from VM function loop, then
the result of VM_FRAME_TYPE_FINISH_P(cfp) is true.
`leave' instruction checks this flag every time.
I measured performance on it. However on my environments,
it improves some benchmarks and slows some benchmarks down.
Maybe it is because of C compiler optimization parameters.
I'll re-visit here if this cause problems.
* insns.def (leave, finish): remove finish instruction.

dfp (dynamic frame pointer) to ep (environment pointer).
This change make VM `normal' (similar to other interpreters).
Before this commit:
Each frame has two env pointers lfp and dfp. lfp points
local environment which is method/class/toplevel frame.
lfp[0] is block pointer.
dfp is block local frame. dfp[0] points previous (parent)
environment pointer.
lfp == dfp when frame is method/class/toplevel.
You can get lfp from dfp by traversing previous environment
pointers.
After this commit:
Each frame has only `ep' to point respective enviornoment.
If there is parent environment, then ep[0] points parent
envioenment (as dfp). If there are no more environment,
then ep[0] points block pointer (as lfp). We call such ep
as `LEP' (local EP). We add some macros to get LEP and to
detect LEP or not.
In short, we replace dfp and lfp with ep and LEP.
rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
and member `ep' is added.
rename rb_thread_t's member `local_lfp' and `local_svar' to
`root_lep' and `root_svar'.
(VM_EP_PREV_EP(ep)): get previous environment pointer. This macro
assume that ep is not LEP.

to solve an issue reported at [ruby-dev:44413] [Ruby 1.9 - Bug #5217].
Before this fix, each instruction has an information including
line number (iseq::iseq_insn_info_table). Instead of this data
structure, recording only line number changing places
(iseq::iseq_line_info_table).
The order of entries in iseq_line_info_table is ascending order of
iseq_line_info_table_entry::position. You can get a line number
by an iseq and a program counter with this data structure.
This fix reduces memory consumption of iseq (bytecode).
On my measurement, a rails application consumes 21.8MB for
iseq with this fix on the 32bit CPU. Without this fix, it
consumes 24.7MB for iseq [ruby-dev:44415].
