shrink-wrap: Remove complicated simple_return manipulations
Now that cfgcleanup knows how to optimize with return statements, the
epilogue insertion code doesn't have to deal with it itself anymore.
* function.c (emit_use_return_register_into_block): Delete.
(gen_return_pattern): Delete.
(emit_return_into_block): Delete.
(active_insn_between): Delete.
(convert_jumps_to_returns): Delete.
(emit_return_for_exit): Delete.
(thread_prologue_and_epilogue_insns): Delete all code dealing with
simple_return for shrink-wrapped blocks.
* shrink-wrap.c (try_shrink_wrapping): Insert simple_return at the
end of blocks that need one.
(get_unconverted_simple_return): Delete.
(convert_to_simple_return): Delete.
* shrink-wrap.c (get_unconverted_simple_return): Delete declaration.
(convert_to_simple_return): Ditto.
