In the PR we have a PARALLEL of a move and a compare (a "mr." instruction).
The compare is dead, so single_set on it returns just the move. Then,
simple_move_p returns true; but the instruction does need reloads in this

crypto/aes, hash/crc32: ignore s390x specific files for now
These files are used to select s390x assembler support in the gc

the cmd/asm syntax rather than gas syntax. Mark the files to be ignored
for now, falling back to the default implementations.
