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

Update to match mainline ConstantStruct::get API change. Also, use ConvertType on InitListExprs as they are being converted. This is needed for a forthcoming patch, and improves the IR generated anyway (see additional type names in testcases). This patch also converts a bunch of std::vector's in CGObjCMac to use C arrays. There are a ton more that should be converted as well. llvm-svn: 133413

Standardize the parsing of function type attributes in a way that follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). llvm-svn: 95436
