The representation of a pointer-to-member in the MS ABI is governed by the layout of the relevant class or if a model has been explicitly specified. If no model is specified, then an appropriate "worst-case-scenario" model is implicitly chosen if, and only, if the pointer-to-member type's representation was needed. Debug info cannot force a pointer-to-member type to have a representation so do not try to query the size of such a type unless we know it is safe to do so. llvm-svn: 238259
