aarch64: Improve epilogue unwind info
* config/aarch64/aarch64.c (aarch64_popwb_single_reg): Remove.
(aarch64_popwb_pair_reg): Remove.
(aarch64_set_frame_expr): Remove.
(aarch64_restore_callee_saves): Add CFI_OPS argument; fill it with
the restore ops performed by the insns generated.
(aarch64_expand_epilogue): Attach CFI_OPS to the stack deallocation
insn. Perform the calls_eh_return addition later; do not attempt to
preserve the CFA in that case. Don't use aarch64_set_frame_expr.
(aarch64_expand_prologue): Use REG_CFA_ADJUST_CFA directly, or no
special markup at all. Load cfun->machine->frame.hard_fp_offset
into a local variable.
(aarch64_frame_pointer_required): Don't check calls_alloca.
