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=c89 -Eonly -verify -pedantic-errors`

this is really just a recommendation, not a requirement. llvm-svn: 69416 2009-04-18 10:25:14 +08:00			`#define foo2!bar /* expected-warning {{whitespace recommended after macro name}} */`
