  -----------
  [AIX] diagnose invalid feature strings on the target attribute (#208059)

Currently, Sema calls `getTargetInfo().isValidFeatureName(S)` to
validate string inputs on the `target` attribute. `PPCTargetInfo`
doesn't override the function and the base class implementation returns
true unconditionally. This results in the FE accepting invalid feature
strings on `target` attribute, and generates invalid target-feature
values in the IR.
