    rs6000: Eliminate zext fed by vclzlsbb [PR111480]

    As PR111480 shows, commit r14-4079 only optimizes the case
    of vctzlsbb but not for the similar vclzlsbb.  This patch
    is to consider vclzlsbb as well and avoid the failure on
    the reported test case.  It also simplifies the patterns
    with iterator and attribute.

            PR target/111480

    gcc/ChangeLog:

            * config/rs6000/vsx.md (VCZLSBB): New int iterator.
            (vczlsbb_char): New int attribute.
            (vclzlsbb_<mode>, vctzlsbb_<mode>): Merge to ...
            (vc<vczlsbb_char>zlsbb_<mode>): ... this.
            (*vctzlsbb_zext_<mode>): Rename to ...
            (*vc<vczlsbb_char>zlsbb_zext_<mode>): ... this, and extend it to
            cover vclzlsbb.

Should be fixed.
