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.

Can I apply it to the mainline?  I have tested this on a big endian power8
system (using --with-cpu=power8), a little endian power9 system (using
--with-cpu=power9), and on a power10 prototype (using --with-cpu=power10).  The
pr86731-fwrapv-longlong.c test passes in all cases.

That doesn't look like what you meant to do... That would accept "lx" 
among other strings...

Thanks,
