keyword arguments/parameters and a splat argument.
[Feature #10440] (Details are described in this ticket)
Most of complex part is moved to vm_args.c.
Now, ISeq#to_a does not catch up new instruction format.
* vm_core.h: change iseq data structures.
* introduce rb_call_info_kw_arg_t to represent keyword arguments.
* add rb_call_info_t::kw_arg.
* rename rb_iseq_t::arg_post_len to rb_iseq_t::arg_post_num.
* rename rb_iseq_t::arg_keywords to arg_keyword_num.
* rename rb_iseq_t::arg_keyword to rb_iseq_t::arg_keyword_bits.
to represent keyword bitmap parameter index.
This bitmap parameter shows that which keyword parameters are given
or not given (0 for given).
It is refered by `checkkeyword' instruction described bellow.
* rename rb_iseq_t::arg_keyword_check to rb_iseq_t::arg_keyword_rest
to represent keyword rest parameter index.
* add rb_iseq_t::arg_keyword_default_values to represent default
keyword values.
* rename VM_CALL_ARGS_SKIP_SETUP to VM_CALL_ARGS_SIMPLE
to represent
(ci->flag & (SPLAT|BLOCKARG)) &&
ci->blockiseq == NULL &&
ci->kw_arg == NULL.
* vm_insnhelper.c, vm_args.c: rewrite with refactoring.
* rewrite splat argument code.
* rewrite keyword arguments/parameters code.
* merge method and block parameter fitting code into one code base.
* vm.c, vm_eval.c: catch up these changes.
* compile.c (new_callinfo): callinfo requires kw_arg parameter.
* compile.c (compile_array_): check the last argument Hash object or
not. If Hash object and all keys are Symbol literals, they are
compiled to keyword arguments.
* insns.def (checkkeyword): add new instruction.
This instruction check the availability of corresponding keyword.
For example, a method "def foo k1: 'v1'; end" is cimpiled to the
following instructions.
0000 checkkeyword 2, 0 # check k1 is given.
0003 branchif 9 # if given, jump to address #9
0005 putstring "v1"
0007 setlocal_OP__WC__0 3 # k1 = 'v1'
0009 trace 8
0011 putnil
0012 trace 16
0014 leave
* insns.def (opt_send_simple): removed and add new instruction
"opt_send_without_block".
* parse.y (new_args_tail_gen): reorder variables.
Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
has parameter variables "k1, kr1, k2, &b, internal_id, krest",
but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
(locate a block variable at last)
* parse.y (vtable_pop): added.
This function remove latest `n' variables from vtable.
* iseq.c: catch up iseq data changes.
* proc.c: ditto.
* class.c (keyword_error): export as rb_keyword_error().
* common.mk: depend vm_args.c for vm.o.
* hash.c (rb_hash_has_key): export.
* internal.h: ditto.

* compile.c (iseq_build_from_ary_exception): move RB_GC_GUARD
(iseq_build_from_ary_body): use PRIsVALUE instead of RB_GC_GUARD
Currently unused functions, but we should set good examples for
using RB_GC_GUARD (and favoring PRIsVALUE in format strings).

* compile.c (iseq_set_arguments): store local variable IDs in
temporary list as Symbols. previously these are stored as
Fixnums to prevent from GC, but IDs of dynamic symbols can
exceed Fixnum range and cause RangeError at inverting from
Fixnum. [ruby-dev:48564] [Bug #10266]

This keeps ci->flag and ci->aux.index consistent across 32-bit
and 64-bit platforms.
ci->flag: VM_CALL_* flags only use 9 bits, currently
ci->aux.index: 2 billion ivars per class should be enough for anybody
This saves around 50K allocations on "valgrind ruby -e exit" on x86-64
before:
total heap usage: 48,122 allocs, 19,253 frees, 8,099,197 bytes allocated
after:
total heap usage: 48,069 allocs, 19,214 frees, 8,047,266 bytes allocated
* vm_core.h (rb_call_info_t): ci->flag becomes 32-bit unsigned int
ci->index becomes a 32-bit signed int (from signed long).
Reorder for better packing on 64-bit, giving an 8 byte reduction
from 104 to 96 bytes for each ci.
* compile.c (new_callinfo, setup_args, iseq_compile_each,
iseq_build_from_ary_body): adjust for type changes
* vm_insnhelper.c (vm_getivar): ditto

Needless conversions made the code harder to follow.

This reduces the iseq_compile_data_storage header from 32 to 16
bytes on 64-bit systems.
pos and size fields cannot exceed 32-bit sizes due to stack size
limits. Using a flexible array for the buffer also saves us 8
bytes of pointer overhead.

iseq_size and line_info_size may be 32-bit.
4GB instruction sequences should be big enough for anyone.
Other existing line info counters are 32-bit, and nobody
should need all that.

Most iseq do not have a catch_table, so avoid needlessly adding
4-8 bytes to the struct for the common case.
Changes from v2:
- iseq_catch_table_size removed, use if (...) for (;...;)
Changes from v1:
- renamed iseq->_catch_table to iseq->catch_table
- iseq_catch_table_bytes: made a static inline function
- iseq_catch_table_size: new function replaces the
iseq_catch_table_each iterator macro

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.

rb_clear_constant_cache

RARRAY_RAWPTR(ary) returns (const VALUE *) type pointer and
usecase of this macro is not acquire raw pointer, but acquire
read-only pointer. So we rename to better name.
RSTRUCT_RAWPTR() is also renamed to RSTRUCT_CONST_PTR()
(I expect that nobody use it).
