* backport r32669 from trunk.
* proc.c (struct METHOD), gc.c (gc_marks), vm_method.c
(rb_gc_mark_unlinked_live_method_entries): fix SEGV bug.
rb_method_entry_t was free'd even when the method is still on the
stack if it is BMETHOD (i.e., Method#call). This is because
rb_method_entry_t is embedded in struct METHOD. This commit
separates them and marks the live method entries.
See [ruby-core:38449] in detail. fix [Bug #5047] [ruby-core:38171]
