* 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.
