This change adds a new type node, DeducedTemplateSpecializationType, to represent a type template name that has been used as a type. This is modeled around AutoType, and shares a common base class for representing a deduced placeholder type. We allow deduced class template types in a few more places than the standard does: in conditions and for-range-declarators, and in new-type-ids. This is consistent with GCC and with discussion on the core reflector. This patch does not yet support deduced class template types being named in typename specifiers. llvm-svn: 293207
