fixes: Bug #2729
a patch from Kazuki Tsujimoto <kazuki@callcc.net>
This problem is caused by changing dfp (dynamic env pointer)
from saved dfp. Saved dfp is pointed env in VM stack. However,
the dfp can be moved because VM copies env from VM stack to
the heap. At this copying, dfp was also changed. To solve this
problem, I'll try to change throw mechanism (not save target dfp,
but save target cfp).
* bootstraptest/test_flow.rb: add a test for above.

may be needed.

vm_throw): allow "return" and "yield" even in singleton class
definition. based on a patch from wanabe <s.wanabe AT gmail.com>
for "return". [ruby-core:21379] [ruby-dev:40975]

added. Unlinked method entries are collected to
vm->unlinked_method_entry_list. On the GC timing, mark all method
entries which are on all living threads. Only non-marked method
entries are collected. This hack prevents releasing living method
entry.
[Performance Consideration] Since this Method Entry GC (MEGC)
doesn't occuer frequently, MEGC will not be a performance bottleneck.
However, to traverse living method entries, every control frame push
needs to clear cfp->me field. This will be a performance issue
(because pushing control frame is occurred frequently).
Bug #2777 [ruby-dev:40457]
* cont.c (fiber_init): init cfp->me.
* gc.c (garbage_collect): kick rb_sweep_method_entry().

* vm.c (rb_thread_mark): mark cfp->me.
* vm_core.h (rb_thread_t): add a field passed_me.
* vm_core.h (rb_vm_t): add a field unlinked_method_entry_list.
* vm_insnhelper.c (vm_push_frame): clear cfp->me at all times.
* vm_insnhelper.c (vm_call_bmethod): pass me.
* bootstraptest/test_method.rb: add a test.
