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.

Stack overflow check should be done *after* pushing a stack frame.
However, some stack overflow checking codes checked *before*
pushing a stack frame with iseq->stack_max.
To solve this problem, add a new parameter `stack_max' to specify
a possible consuming stack size.

with rb_call_info_t to speedup `attr' getter and setter.
Cached index is stored in rb_call_info_t::aux::index.
`index' == 0 means not cached. `index' > 0 means cached and cached
index is `index - 1'.
* insns.def ((get|set)instancevariable): use new wrapper functions
vm_(get|set)instancevariable() defined in vm_insnhelper.c.
* vm_core.h (rb_call_info_t::aux): introduce new union data because
opt_pc can share with index.

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).

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.

`bp' can be calculate by `sp' (stack pointer) of previous frame.
Now, `bp_check' field is remained for debug. You can eliminate
this field by setting VM_DEBUG_BP_CHECK as 0.
* vm_insnhelper.c (vm_base_ptr): add `vm_base_ptr(cfp).
This function calculates base pointer from cfp.
* vm_insnhelper.c (vm_setup_method): push `recv' value on top of
value stack (before method parameters).
This change is for keeping consistency with normal method dispatch.
* insns.def: fix to use vm_base_ptr().
* vm.c (vm_exec): ditto.
* vm_dump.c: remove `bp' related dumps.
* cont.c (fiber_init): fix to check VM_DEBUG_BP_CHECK.
