to represent execution context [Feature #14038]
* vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer.
There are many code using `th` to represent execution context
(such as cfp, VM stack and so on). To access `ec`, they need to
use `th->ec->...` (adding one indirection) so that we need to
replace them by passing `ec` instead of `th`.
* vm_core.h (GET_EC()): introduced to access current ec. Also
remove `ruby_current_thread` global variable.
* cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of
rb_context_t::thread_value.
* cont.c (ec_set_vm_stack): added to update vm_stack explicitly.
* cont.c (ec_switch): added to switch ec explicitly.
* cont.c (rb_fiber_close): added to terminate fibers explicitly.

This change is for future JIT compiler introduction.
See r60231 for the purpose.

vm_insnhelper.h: ditto.
All changes are for reducing changes required to introduce JIT compiler.
Unlike functions that can be inlined by header, those variables should
be shared with JIT-ed code. This will help reducing cost of rebase
against upstream.

* vm_core.h: Ruby processes run with two stacks, a machine stack and a
VM stack. To make it clear, this fix renames
rb_execution_context_t::stack(_size) to vm_stack(_size).

The goal is to reduce rb_context_t and rb_fiber_t size
by removing the need to store the entire rb_thread_t in
there.

* vm.c: get return_value from imemo_throw_data object (THROW_DATA_VAL()).
imemo_throw_data (TAG_BREAK) contains returned value.
However, imemo_throw_data (TAG_BREAK) can skip several frames so that
we need to use it only once (at most internal frame). To record it,
we introduced THROW_DATA_CONSUMED and check it.
* internal.h: define THROW_DATA_CONSUMED flag.
* test/ruby/test_settracefunc.rb: add tests for [Bug #13369]
* vm_insnhelper.h: add THROW_DATA_CONSUMED_P() and
THROW_DATA_CONSUMED_SET().

[Bug #12628]
This patch introduce many changes.
* Introduce concept of "Block Handler (BH)" to represent
passed blocks.
* move rb_control_frame_t::flag to ep[0] (as a special local
variable). This flags represents not only frame type, but also
env flags such as escaped.
* rename `rb_block_t` to `struct rb_block`.
* Make Proc, Binding and RubyVM::Env objects wb-protected.
Check [Bug #12628] for more details.

* rb_call_info (ci) has compiled fixed information.
* if ci->flag & VM_CALL_KWARG, then rb_call_info is
also rb_call_info_with_kwarg. This technique reduce one word
for major rb_call_info data.
* rb_calling_info has temporary data (argc, blockptr, recv).
for each method dispatch. This data is allocated only on
machine stack.
* rb_call_cache is for inline method cache.
Before this patch, only rb_call_info_t data is passed.
After this patch, above three structs are passed.
This patch improves:
* data locarity (rb_call_info is now read-only data).
* reduce memory consumption (rb_call_info_with_kwarg,
rb_calling_info).
* compile.c: use above data.

`flag' contains several categories of attributes and it makes us
confusion (at least, I had confused).
* rb_method_visibility_t (flags::visi)
* NOEX_UNDEF -> METHOD_VISI_UNDEF = 0
* NOEX_PUBLIC -> METHOD_VISI_PUBLIC = 1
* NOEX_PRIVATE -> METHOD_VISI_PRIVATE = 2
* NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
* NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
* NOEX_BASIC -> basic (flags::basic, 1 bit)
* NOEX_MODFUNC -> rb_scope_visibility_t in CREF
* NOEX_SUPER -> MISSING_SUPER (enum missing_reason)
* NOEX_VCALL -> MISSING_VCALL (enum missing_reason)
* NOEX_RESPONDS -> BOUND_RESPONDS (macro)
Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
Background:
I did not know what "NOEX" stands for.
I asked Matz (who made this name) and his answer was "Nothing".
"At first, it meant NO EXport (private), but the original
meaning was gone."
This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
scope visibility.
It has 3 method visibilities (public/private/protected)
and `module_function`.

ruby_vm_global_state_version into two separate counters - one for the
global method state and one for the global constant state. This means
changes to constants do not affect method caches, and changes to
methods do not affect constant caches. In particular, this means
inclusions of modules containing constants no longer globally
invalidate the method cache.
* class.c, eval.c, include/ruby/intern.h, insns.def, vm.c, vm_method.c:
rename rb_clear_cache_by_class to rb_clear_method_cache_by_class
* class.c, include/ruby/intern.h, variable.c, vm_method.c: add
rb_clear_constant_cache
* compile.c, vm_core.h, vm_insnhelper.c: rename vmstat field in
rb_call_info_struct to method_state

* array.c (empty_ary_alloc, ary_new): added array create DTrace probe.
* compile.c (rb_insns_name): allowing DTrace probes to access
instruction sequence name.
* Makefile.in: translate probes.d file to appropriate header file.
* common.mk: declare dependencies on the DTrace header.
* configure.in: add a test for existence of DTrace.
* eval.c (setup_exception): add a probe for when an exception is
raised.
* gc.c: Add DTrace probes for mark begin and end, and sweep begin and

* hash.c (empty_hash_alloc): Add a probe for hash allocation.
* insns.def: Add probes for function entry and return.

* vm_core.h (rb_call_info_t::refinements), compile.c (new_callinfo),
vm_insnhelper.c (vm_search_method): revert r37616 because it's too
slow. [ruby-dev:46477]

If `enable' is 0 then CI_SET_FASTPATH() doesn't work.
And add new configuration option OPT_CALL_FASTPATH. If this macro
was defined by 0, then CI_SET_FASTPATH() doesn't work any more.
* vm_insnhelper.c (vm_call_method): Pass `0' for `enabled' parameter
of CI_SET_FASTPATH if this method is protected.

`CI_SET_FASTPATH(ci, func)'. This macro set `ci->call' as `func'.
`func' (ci->call) is called at the last of `send'
(and `invokesuper') instruction.
`CI_SET_FASTPATH' does not set `ci->call' when the method
(stored in `ci->me') is `protected'.
* vm_insnhelper.c (vm_call_method): use `CI_SET_FASTPATH'.
After several checking (visibility, argc checking), the result of
checking can be reused until re-definition of this method
with inline method cache.
Note that this optimization is now experimental.
If you find any problem about it, please tell us.

use only a `ci' (rb_call_info_t) parameter instead of using
parameters such as `op_id', 'op_argc', `blockiseq' and flag.
These information are stored in rb_call_info_t at the compile
time.
This technique simplifies parameter passings at related
function calls (~10% speedups for simple mehtod invocation at
my machine).
`rb_call_info_t' also has new function pointer variable `call'.
This `call' variable enables to customize method (block)
invocation process for each place. However, it always call
`vm_call_general()' at this changes.
`rb_call_info_t' also has temporary variables for method
(block) invocation.
* vm_core.h, compile.c, insns.def: introduce VM_CALL_ARGS_SKIP_SETUP
VM_CALL macro. This flag indicates that this call can skip
caller_setup (block arg and splat arg).
* compile.c: catch up above changes.
* iseq.c: catch up above changes (especially for TS_CALLINFO).
* tool/instruction.rb: catch up above chagnes.
* vm_insnhelper.c, vm_insnhelper.h: ditto. Macros and functions
parameters are changed.
* vm_eval.c (vm_call0): ditto (it will be rewriten soon).

This data structure contains information including inline method
cache. After that, `struct iseq_inline_cache_entry' does not
need to contain inline cache for method invocation.
Other information will be added to this data structure.
* vm_core.h (rb_iseq_t): add `callinfo_entries' and `callinfo_size'
members to `rb_iseq_t'.
* insns.def, compile.c: Use CALL_INFO instead of IC.
* tool/instruction.rb: support CALL_INFO as operand type.
* vm_insnhelper.c, vm_insnhelper.h: ditto.

hooks (old macro name is COLLECT_USAGE_ANALYSIS).
This feature is only for VM developers. (I'm not sure I can use
`VM developers' (the plural form) in this sentence).
If VM_COLLECT_USAGE_DETAILS is not 0, VM enables the following
usage collection features:
(1) insntruction: collect intruction usages.
(2) operand: collect operand usages.
(3) register: collect register usages.
The results are stored in
RubyVM::USAGE_ANALYSIS_INSN for (1, 2),
RubyVM::USAGE_ANALYSIS_INSN_BIGRAM for (1) and
RubyVM::USAGE_ANALYSIS_REGS for (3).
You can stop collecting usages with
RubyVM::USAGE_ANALYSIS_INSN_STOP(),
RubyVM::USAGE_ANALYSIS_OPERAND_STOP(),
RubyVM::USAGE_ANALYSIS_REGISTER_STOP()
for (1), (2), (3) respectively.
You can also change the hook functions by setting
C level global variables
`ruby_vm_collect_usage_func_(insn|operand|register)'
for (1), (2), (3) respectively.
See codes for more details.
* tool/instruction.rb: fix macro names.
* iseq.c (insn_operand_intern): make it export (used in vm.c).
fix to skip several processes if not needed (pointer is 0).
* vm_dump.c: move codes for collection features to vm.c.
* vm_exec.h: rename macro and function names.
* vm_insnhelper.h: ditto.
