--- Comment #5 from Simon Pilgrim <llvm-dev at redking.me.uk> ---
Resolving the 'allof' MOVMSK(PCMPEQ(x,0)) == -1 pattern now uses PTEST if its
available.

The 'anyof' cases still must use MOVMSK as there isn't a PTEST equivalent that
wouldn't involve still doing the PCMPEQ, which is never quicker than the MOVMSK
path on any existing hardware.
