Parse: Don't crash on trailing whitespace before EOF Parser::ParseDeclarationSpecifiers eagerly updates the source range of the DeclSpec with the current token position. However, it might not consume any more tokens. Fix this by only setting the start of the range, not the end. This way the SourceRange will be invalid if we don't consume any more tokens. This fixes PR20413. Differential Revision: http://reviews.llvm.org/D4646 llvm-svn: 214018

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.
