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 -triple x86_64-apple-darwin9 -emit-llvm -o %t %s`
Add implicit definition of objc_msgSend. - As with malloc and friends, this is important where the return type on a 64-bit platform would otherwise end up discarding the upper 32-bits. llvm-svn: 69874 2009-04-23 15:00:09 +08:00			`// RUN: grep -F 'declare i8* @objc_msgSend(...)' %t`
