pointer against g->stackguard to check for overflow.  To cut one
instruction from the check sequence for functions with tiny frames,
the stack is allowed to protrude StackSmall bytes below the stack
guard.  Functions with large frames don't bother with the check and
always call morestack.  The sequences are (for amd64, others are
similar):

	guard = g->stackguard
	frame = function's stack frame size
