1. The PR proceeds with a backend target hook to allow front-ends to
determine what target features are available in a compilation based on
the CPU name.
2. Fix a backend target feature bug that supports HTM for
Power8/9/10/11. However, HTM is only supported on Power8/9 according to
the ISA.
3. All target features that are hardcoded in PPC.cpp can be retrieved
from the backend target feature. I have double-checked that the
hardcoded logic for inferring target features from the CPU in the
frontend(PPC.cpp) is the same as in PPC.td.

The reland patch addressed the comment
