Implement GCNSubtarget::checkSubtargetFeatures as a canonical place to check subtarget features for consistency and diagnose any inconsistencies. To start with, the implementation just checks that either wavefrontsize32 or wavefrontsize64 is selected. checkSubtargetFeatures is called at the start of instruction selection. This is pretty arbitrary. It is just a convenient point at which we have access to the subtarget that we're going to use for codegenning a particular function.
