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). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8 2009-12-15 23:14:24 +03:00			`// RUN: %clang_cc1 %s -E 2>&1 \| grep warning \| wc -l \| grep 2`

Fix PR2279 part C: shifts don't perform the UACs, thanks to Neil for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50624 91177308-0d34-0410-b5e6-96231b3b80d8 2008-05-04 22:25:32 +04:00			`// Shifts don't want the usual conversions: PR2279`
