* reload.c (find_reloads_address_1): Mention dependency on
gen_reload.
* reload1.c (gen_reload): For IN with an unary operation, try
moving inner expression to OUT if trivial SET is not valid.
Confirm that the result is valid. Move common code block into...
(emit_insn_if_valid_for_reload): New function.
