* vm_core.h (RUBY_VM_SET_TIMER_INTERRUPT, RUBY_VM_SET_INTERRUPT,
RUBY_VM_SET_FINALIZER_INTERRUPT): use atomic ops for preventing
interrupt_flag bit lost.
* thread.c (rb_threadptr_execute_interrupts_rec): ditto.
* vm_core.h (typedef struct rb_thread_struct): change type of
interrupt_flag to rb_atomic_t.
* atomic.h: move atomic ops definition from signal.c.
* signal.c: remove atomic ops definition.
* common.mk (gc, signal, thread, cont): add to dependency to atomic.h.
