because there is a same name (no related) function gc_stat().
Also gc_stat_* are renamed to gc_mode_*,
gc_stat_transition() to gc_mode_transition(),
rb_objspace:🎏:stat is renamed to rb_objspace:🎏:mode.
Change rb_objspace:🎏:mode from 2 bits to 3 bits because VC++
returns negative enum value with 2 bits.
* gc.c (gc_mode): add a macro to access rb_objspace:🎏:mode
with verification code (verification is enabled only on
RGENGC_CHECK_MODE > 0).
* gc.c (gc_mode_set): same macro for setter.

a page).

whether a page is in a tomb or not. Instead of this field,
heap_page:🎏:in_tomb (1 bit field) is added.
Also type of heap_page::(total|free|final)_slots are changed from
int to short. 2B is enough for them.

new object.

rb_wb_protected_newobj_of(), pass the WB_PROTECTED
information explicitly.
* internal.h: use introduced functions by NEWOBJ_OF().
`flag' is immediate value, so that C compilers can
solve them at compile time.
* include/ruby/ruby.h: add a commnent about that.

boolean flag value.

by Kazuho Oku <kazuho@natadeco.co>.
This pull request has the following commits.
* gc.c: reduce # of args to 6 (max. of register args on x86-64) so
that the `newobj_of_slowpass` can be called via TCO.
* gc.c (newobj_of), string.c (str_duplicate): for performance,
the hot functions must be inlined.
* gc.c: for performance, preceding arguments of `.*newobj_of.*`
must be same, so that the arg registers can be reused in case of
TCO.

to avoid register savings for fast path.
This idea is given by Kazuho Oku <kazuho@natadeco.co>.
