Can you
get_frame_size () returns used stack slots during compilation, which
may be optimized out later. This patch does the followings:
1. Add no_stack_frame to machine_function to indicate that the function
doesn't need a stack frame.
2. Change ix86_find_max_used_stack_alignment to set no_stack_frame.
