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 -fsyntax-only -verify %s`

Really trivial patch to accept pointer to const void in indirect goto. Despite the lack of documentation, this matches the behavior of GCC. llvm-svn: 94954 2010-01-31 18:26:25 +08:00			`void const* l1_ptr = &&l1;`
			`goto *l1_ptr;`
