intended for redeclarations, fixing those that need it. Fixes PR6831. This uncovered an issue where the C++ type-specifier-seq parsing logic would try to perform name lookup on an identifier after it already had a type-specifier, which could also lead to spurious ambiguity errors (as in PR6831, but with a different test case). llvm-svn: 101419
