Use intrinsic pattern to make a simpler match

Browse Source 
This is a follow-on to r236740 where I took Andrea's advice
in D9504 to remove a redundant pattern...except that I removed
the wrong pattern!

AFAICT, there is no change in the final code produced because 
subsequent passes would clean up the extra instructions created
by the more complicated pattern.
