Don't enter a qualified scope for an invalid decl. Fixes assertion later on. rdar://9122937 & http://llvm.org/PR9459 llvm-svn: 130006

// RUN: %clang_cc1 -fsyntax-only -verify %s
// Don't crash.
Improve recovery from invalid template-ids. Instead of bailing out of parsing when we encounter an invalid template-name or template arguments in a template-id, produce an annotation token describing the invalid construct. This avoids duplicate errors and generally allows us to recover better. In principle we should be able to extend this to store some kinds of invalid template-id in the AST for tooling use, but that isn't handled as part of this change.

PR10359: Template declarations which define classes are not permitted to also contain declarators. Previously we would accept code like this: template<typename T> struct S { } f() { return 0; } This case now produces a missing ';' diagnostic, since that seems like a much more likely error than an attempt to declare a function or variable in addition to the class template. Treat this llvm-svn: 135195
