    Fix regular expression error in PR 100166 patch
    
    In my patch for PR testsuite/100166 (which fixes various tests so that the
    plxv and pstxv instructions can be counted as legitimate instructions), I
    had a typo in the pr86731-fwrapv-longlong.c test (using plvx instead of
    plxv).  This patch fixes this error.
