Matt Arsenault e5bbaa9c8f PPC: Split 64bit target feature into 64bit and 64bit-support (#157206) ...

This was being used for 2 different purposes.

The TargetMachine constructor prepends +64bit based on isPPC64
triples as a mode switch. The same feature name was also explicitly
added to different processors, making it impossible to perform a pure
feature check for whether 64-bit mode is enabled ir not. i.e.,
checkFeatures("+64bit") would be true even for ppc32 triples.

The comment in tablegen suggests it's relevant to track which processors
support 64-bit mode independently of whether that's the active compile
target, so replace that with a new feature.
