nested names as id-expressions, using the annot_primary_expr annotation, where possible. This removes some redundant lookups, and also allows us to typo-correct within tentative parsing, and to carry on disambiguating past an identifier which we can determine will fail lookup as both a type and as a non-type, allowing us to disambiguate more declarations (and thus offer improved error recovery for such cases). This also introduces to the parser the notion of a tentatively-declared name, which is an identifier which we *might* have seen a declaration for in a tentative parse (but only if we end up disambiguating the tokens as a declaration). This is necessary to correctly disambiguate cases where a variable is used within its own initializer. llvm-svn: 162159
