    arm: fully validate mem_noofs_operand [PR120351]

    It's not enough to just check that a memory operand is of the form
    mem(reg); after RA we also need to validate the register being used.
    The safest way to do this is to call memory_operand.

            PR target/120351

    gcc/ChangeLog:

            * config/arm/predicates.md (mem_noofs_operand): Also check the op
            is a valid memory_operand.

    gcc/testsuite/ChangeLog:

            * gcc.target/arm/pr120351.c: New test.
