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 -std=c++0x -verify %s`
Deal with an icky corner case where we were complaining that a catch statement was using an rvalue reference during the template definition. However, template instantiations based on an lvalue reference type are well-formed, so we delay checking of these property until template instantiation time. llvm-svn: 72041 2009-05-19 05:08:14 +08:00
