[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.
