All symbols have an fstring entry, and we initialize symbol tables
with 1000 bins. This reduces resizes during startup.

We may tag the running_thread pointer to avoid making the "once" struct
bigger than "struct iseq_inline_cache_entry".
This only saves a small amount with "valgrind ruby -e exit"
before:
total heap usage: 48,122 allocs, 19,248 frees, 8,110,149 bytes allocated
after:
total heap usage: 48,122 allocs, 19,253 frees, 8,099,197 bytes allocated
* insns.def (once): define and use fake RUNNING_THREAD_ONCE_DONE
pointer to indicate is->once.running_thread is done.
* vm_core.h (iseq_inline_storage_entry): remove done field,
allowing the union to be reduced from 24=>16 bytes on 64-bit

RUBY_INTERNAL_EVENT_GC_ENTER and
RUBY_INTERNAL_EVENT_GC_EXIT.
When invoking GC process, GC_ENTER event is called.
When exiting from GC process, GC_EXIT event is called.
Incremental GC (incremental marking and lazy sweep) can call
these events many times.
For example (minor marking):
(1) GC_ENTER
- (2) GC_START (minor GC)
(minor marking)
- (3) GC_END_MARK
(start lazy sweep)
(4) GC_EXIT
(ruby process)
(5) GC_ENTER
(lazy sweep)
(6) GC_EXIT
(ruby process)
(... repeat (5), (6))
(7) GC_ENTER
(finish lazy sweep)
- (8) GC_END_SWEEP
(9) GC_EXIT
2nd example (incremental major marking):
(1) GC_ENTER
- (2) GC_START (minor GC)
(start incremental marking)
(3) GC_EXIT
(ruby process)
(4) GC_ENTER
(incremental marking)
(5) GC_EXIT
(ruby process)
(... repeat (4), (5))
(6) GC_ENTER
(finish incremental marking)
- (7) GC_END_MARK
(start lazy sweep)
(8) GC_EXIT
(ruby process)
(9) GC_ENTER
(lazy sweep)
(10) GC_EXIT
(ruby process)
(... repeat (9), (10))
(11) GC_ENTER
(finish lazy marking)
- (12) GC_STOP_SWEEP
(13) GC_EXIT
Thease internal events enable to measure GC pause time completely.

In addition to being unaffected by _offset_ correction,
CLOCK_MONOTONIC_RAW is also unaffected by _frequency_ correction,
making it unsuitable for measuring real time on systems where the
clock is always running too fast or slow.
CLOCK_MONOTONIC (without _RAW) is the correct clock, as it is unaffected
by _offset_ correction (due to human error or battery replacement), but
still takes _frequency_ correction into account for clocks which
consistently run too fast or slow.
Thanks to Vít Ondruch for reporting the issue on ARM [Bug #10202]

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

running "ruby -rpp -e 'pp GC.stat'", a reduction in
malloc usage is shown:
before:
:malloc_increase=>118784,
:oldmalloc_increase=>1178736,
after:
:malloc_increase=>99832,
:oldmalloc_increase=>1031976,
For "ruby -e exit", valgrind reports over 300K reduction in
overall allocations (and unnecessary memory copies).
before:
total heap usage: 49,622 allocs, 20,492 frees, 8,697,493 bytes allocated
after:
total heap usage: 48,935 allocs, 19,805 frees, 8,373,773 bytes allocated
(numbers from x86-64)
v2 changes based on ko1 recommendations [ruby-core:64883]:
- squashed in-place direct thread translation to avoid alloc+copy
- renamed rb_iseq_untranslate_threaded_code to rb_iseq_original_iseq,
cache new iseq->iseq_original field.
* compile.c (rb_iseq_translate_threaded_code): modify in-place w/o copy
(rb_vm_addr2insn): new function for debug
(rb_iseq_original_iseq): ditto
(iseq_set_sequence): assign iseq_encoded directly
[Feature #10185]
* vm_core (rb_iseq_t): move original ->iseq to bottom
* iseq.c (iseq_free, iseq_free): adjust for new layout
(rb_iseq_disasm): use original iseq for dump
(iseq_data_to_ary): ditto
(rb_iseq_line_trace_each): ditto
(rb_iseq_build_for_ruby2cext): use iseq_encoded directly
* vm_dump.c (rb_vmdebug_debug_print_pre): use original iseq

ruby_gc_stressfull will speedup newobj_of() slightly.
* gc.c: initialize ruby_gc_stress(full|_mode) by gc_params.gc_stress
even if ENABLE_VM_OBJSPACE is false.
