follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). llvm-svn: 95436
