Don't warn function alignment if warn_if_not_aligned_p is true
When warn_if_not_aligned_p is true, a warning will be issued on function declaration later. There is no need to warn function alignment when warn_if_not_aligned_p is true. * c-attribs.c (common_handle_aligned_attribute): Don't warn function alignment if warn_if_not_aligned_p is true.
