DeclRefExprs and BlockDeclRefExprs into a single function Sema::ActOnDeclarationNameExpr, eliminating a bunch of duplicate lookup-name-and-check-the-result code. Note that we still have the three parser entry points for identifiers, operator-function-ids, and conversion-function-ids, since the parser doesn't (and shouldn't) know about DeclarationNames. This is a Good Thing (TM), and there will be more entrypoints coming (e.g., for C++ pseudo-destructor expressions). llvm-svn: 59527
