When handling a member access into a non-class, non-ObjC-object type, we would perform a lookup into the surrounding scope as if for an unqualified lookup. If the member access was followed by a '<' and this lookup (or the typo-correction for it) found a template name, we'd treat the member access as naming that template. Now we treat such accesses as never naming a template if the type of the object expression is of vector type, so that vector component accesses are never misinterpreted as naming something else. This is not entirely correct, since it is in fact valid to name a template from the enclosing scope in this context, when invoking a pseudo-destructor for the vector type via an alias template, but that's very much a corner case, and this change leaves that case only as broken as the corresponding case for Objective-C types is. This incidentally adds support for dr2292, which permits a 'template' keyword at the start of a member access naming a pseudo-destructor. llvm-svn: 368940
