* configure.in: add --enable-valgrind.
* gc.h (SET_MACHINE_STACK_END): new macro to replace
rb_gc_set_stack_end. it find out accurate stack boundary by
asm using gcc on x86.
* thread.c (rb_gc_set_stack_end): don't define if asm-version
SET_MACHINE_STACK_END is available.
* gc.c (mark_current_thread): extracted from garbage_collect.
it use SET_MACHINE_STACK_END to not scan out of stack area.
it notify conservative GC information to valgrind if
--enable-valgrind.
