Some callable method entries (cme) can be a key of
overloaded_cme_table
and the keys should be pinned because the table is numtable (VALUE is a key).
Before the patch GC checks the cme is in
overloaded_cme_table
by looking upthe table, but it needs VM locking.
It works well in normal GC marking because it is protected by the VM lock,
but it doesn't work on
rb_objspace_reachable_objects_from
because it doesn'tuse VM lock.
Now, the number of target cmes are small enough, I decide to pin down
all possible cmes instead of using looking up the table.
