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 -std=gnu89 -pedantic -fsyntax-only -verify`
restrict is not a keyword in gnu89 mode. Change TokenKinds.def to reflect that. llvm-svn: 72500 2009-05-28 06:48:34 +08:00
