I agree with Matt. We already have fillAMDGPUFeatureMap() that is supposed to
fill the default features. On line 434/435, it already fills wave32/64 for
spirv. It is kind of redundant and may cause inconsistency to have
isWave32Capable() and isWave64Capable(). If we need a way to get wave64
capability, we could cache the default target features returned by
fillAMDGPUFeatureMap() in TargetInfo and look it up for wave64 capability.
