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).
