The sh port does not encode information about epilogues in the unwind info.
See PR target/29997 for context.
In addition to adding saving / restoring state around epilogues, the
current measures to prevent unwind info for epilogues to be emitted must be
reverted:
output_stack_adjust: set emit_fn depending always to frame_insn
add REG_FRAME_RELATED_EXPR notes independent of epilogue_p
pop: use frame_insn instead of emit_insn
sh_expand_epilogue: should add REG_FRAME_RELATED_EXPR notes and use frame_insn
like sh_expand_prologue does.
