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 2009-12-15 20:14:24 +00:00			`// RUN: %clang_cc1 -emit-llvm %s -o - -triple i686-pc-linux-gnu \| grep "bitcast (%0\* @r to %union.x\*), \[4 x i8\] undef"`
