cont.c: Optimize fiber_switch callees
Remove some unnecessary VALUE/struct conversions and aggressively inline
functions used during fiber_switch. Either of these changes alone does
not yield significant performance increase, but in combination they
improve performance by ~6%.
Arguably, removal of separate VALUE/rb_fiber_t* variables also makes the
code more readable in a few places.
* vm_core.h: declare rb_fiber_t typedef
(rb_thread_t): fiber and root_fiber become rb_fiber_t * (from VALUE)
* vm.c (rb_thread_mark): use rb_fiber_mark_self
* cont.c (rb_fiber_t): prev becomes rb_fiber_t * (from VALUE)
(cont_mark, cont_free): simplify conditions
(rb_fiber_mark_self): new function
(fiber_mark): use rb_fiber_mark_self
(cont_save_thread, cont_restore_thread): inline
(cont_restore_thread): simplify
(fiber_setcontext): simplify conditions
(rb_cont_call): remove dereference
(fiber_t_alloc): update for rb_fiber_t->prev type change
(rb_fiber_start): ditto
(fiber_current): extract from rb_fiber_current
(return_fiber): move, simplify type checks
(rb_fiber_current): use fiber_current
(fiber_store): simplify type checks
(fiber_switch): ditto, simplify call to fiber_setcontext,
use fiber_current
(rb_fiber_transfer): update for type changes
(rb_fiber_terminate): move, use fiber_switch
(rb_fiber_resume): update for type changes
(rb_fiber_reset_root_local_storage): ditto
(rb_fiber_yield): use rb_fiber_switch instead of rb_fiber_transfer
(rb_fiber_m_transfer): ditto
