re PR target/53038 (cfi_restore for cr before cr is actually restored)
PR target/53038
* config/rs6000/rs6000.c (load_lr_save, restore_saved_lr,
load_cr_save, add_crlr_cfa_restore): New functions.
(rs6000_restore_saved_cr): Rename to..
(restore_saved_cr): ..this. Add cfa_restore notes for cr.
(rs6000_emit_epilogue): Use new functions. Adjust condition
for emitting lr and cr cfa_restore. Emit cfa_restores for fp
regs when using out-of-line restore only when shrink wrapping.
