Richard Smith f86b0ae196 PR13433: In Microsoft mode, don't require function calls within decltype
expressions to have complete return types (or accessible destructors). If the
return type is required to be complete for some other reason (for instance, if
it is needed by overload resolution), then it will still be required to be
complete. This is apparently required in order to parse a MSVC11 header.
