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

fix rdar://7466570 - Be more bug compatible with GCC when it comes to expanding directives withing macro expansions. This is undefined behavior according to 6.10.3p11, so we might as well be undefined in ways similar to GCC. llvm-svn: 91266
