    Enhance tst-xmmymm.sh to detect zmm register usage in ld.so (BZ #16194)

    2d63a517e4084ec80403cd9f278690fa8b676cc4 added support to save and
    restore zmm register in the dynamic linker, but did not enhance
    test-xmmymm.sh to detect accidental usage of these registers.  The
    patch below adds that check.

    The script has also been renamed to tst-ld-sse-use.sh.  To see the
    minimal changes, run `git show -M`.

        [BZ #16194]
        * sysdeps/x86/tst-xmmymm.sh: Rename file to...
        * sysdeps/x86/tst-ld-sse-use.sh: ... this.  Check for zmm
        register usage.
        * sysdeps/x86/Makefile: Adjust.
