Fix infinite loop in ensure after NoMemoryError

VM patch from wanabe.

Test based on example from buzztaiki (Taiki Sugawara).

Test fails when compiles with -DRUBY_DEBUG, as that can
can use rb_bug instead of NoMemoryError, which doesn't
allow testing this case. Test also fails on MingW, as
RangeError is used instead of NoMemoryError. Skip the
test in either case.

Fixes [Bug #15779]
