x86: Don't use get_frame_size when finalizing stack frame
get_frame_size () returns used stack slots during compilation, which
may be optimized out later. Since ix86_find_max_used_stack_alignment
is called by ix86_finalize_stack_frame_flags to check if stack frame
is required, there is no need to call get_frame_size () which may give
inaccurate final stack frame size.
Tested on AVX512 machine configured with
--with-arch=native --with-cpu=native
