    IBM Z: Handle hard registers in s390_md_asm_adjust()

    gen_fprx2_to_tf() and gen_tf_to_fprx2() cannot handle hard registers,
    since the subregs they create do not pass validation.  Change
    s390_md_asm_adjust() to manually copy between hard VRs and FPRs instead
    of using these two functions.

    gcc/ChangeLog:

            * config/s390/s390.c (s390_hard_fp_reg_p): New function.
            (s390_md_asm_adjust): Handle hard registers.
