We may tag the running_thread pointer to avoid making the "once" struct

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

Cached index is stored in rb_call_info_t::aux::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.

caller_setup (block arg and splat arg).

* iseq.c: catch up above changes (especially for TS_CALLINFO).
* tool/instruction.rb: catch up above chagnes.

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.
