i386: Use const reference of struct ix86_frame to avoid copy
We can use const reference of struct ix86_frame to avoid making a local
copy of ix86_frame. ix86_expand_epilogue makes a local copy of struct
ix86_frame and uses the reg_save_offset field as a local variable. This
patch uses a separate local variable for reg_save_offset.
Tested on x86-64 with ada.
PR target/83905
* config/i386/i386.c (ix86_expand_prologue): Use cost reference
of struct ix86_frame.
(ix86_expand_epilogue): Likewise. Add a local variable for
the reg_save_offset field in struct ix86_frame.
