Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'. - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446 2009-12-16 04:14:24 +08:00			`// RUN: %clang_cc1 %s -fsyntax-only -verify`

Handle any undeclared parameters in a K&R-style function with a special action, inside function prototype scope. This avoids confusion when we try to inject these parameters into the scope of the function body before the function itself has been added to the surrounding scope.
