* reload.c (find_reloads): Do not use the mode specified in the insn
pattern as reload mode for address operands. Do not generate optional
reloads for operands where a mandatory reload was already pushed.
Generate optional reloads only in the final pass though find_reloads.
(have_replacement_p): New function.
