* gcse.c (pre_insert_copy_insn): Tweak the logic for finding the
appropriate set to match that in hash_scan_insn. Fall back to
the original copy method, if we can't validate changing insn.
(pre_delete): Only delete instructions that have a single_set,
instead of aborting when we encounter an PARALLEL insn with more
then one SET.
