gc.c: Use the non-recursive marking instead of recursion. The
recursion marking of CRuby needs checking stack overflow and the
fail-safe system, but these systems not good at partial points,
for example, marking deep tree structures. [ruby-dev:46184]
[Feature #7095]
configure.in (GC_MARK_STACKFRAME_WORD): removed. It's used by
checking stack overflow of marking.
