  -----------
  AMDGPU: Validate processor and features in TargetID parsing

TargetID::parseTargetIDString previously only checked that the string was
structurally a 4-component triple followed by a processor field. It
accepted unrecognized processors and silently ignored malformed or
unsupported feature modifiers. Work towards improving validation so in
the future clang's copy of TargetID can be replaced.
