[PowerPC] Add new Future CPU for PowerPC in LLVM
This is a continuation of D70262
The previous patch as listed above added the future CPU in clang. This patch
adds the future CPU in the PowerPC backend. At this point the patch simply
assumes that a future CPU will have the same characteristics as pwr9. Those
characteristics may change with later patches.
