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 -dM -undef -Dfoo=1 -E %s \| FileCheck %s`
Implement support for the -undef command line option, patch by Roman Divacky! PR5363 llvm-svn: 85932 2009-11-04 03:50:27 +08:00
