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

// RUN: %clang_cc1 %s -verify -fheinous-gnu-extensions
introduce a new -fheinous-gnu-extensions flag that enables really really horrible extensions that are disabled by default but that can be accepted by -fheinous-gnu-extensions (but which always emit a warning when enabled). As our first instance of this, implement PR3788/PR3794, which allows non-lvalues in inline asms in contexts where lvalues are required. bleh. llvm-svn: 66910
