    s390: Fixup fix for *extzv_<mode>_{srl,sll}<clobbercc_or_nocc>
    
    Since r17-2057 the output template is a statement which means we have to
    annotate the mnemonic.
    
    gcc/ChangeLog:
    
            * config/s390/s390.md: Annotate mnemonic for
            extzv_<mode>_{srl,sll}<clobbercc_or_nocc>.
    
    (cherry picked from commit d2e155986d0ec36b40fe5a9695e18ad7599f1850)
