* config/aarch64/aarch64.c (aarch64_save_or_restore_fprs): Add
cfi_ops argument, for restore put REG_CFA_RESTORE notes into
*cfi_ops rather than on individual insns. Cleanup.
(aarch64_save_or_restore_callee_save_registers): Likewise.
(aarch64_expand_prologue): Adjust caller.
(aarch64_expand_epilogue): Likewise. Cleanup. Emit queued cfi_ops
on the stack restore insn.
