[SystemZ] Use POPCNT instruction on z196 

We already exploit a number of instructions specific to z196,
but not yet POPCNT.  Add support for the population-count
facility, MC support for the POPCNT instruction, CodeGen
support for using POPCNT, and implement the getPopcntSupport
TargetTransformInfo hook.
