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

// RUN: %clang_cc1 -triple i686-apple-darwin9 -fsyntax-only -verify %s
Add Sema implementation of #pragma pack stack. - Follows the MSVC (original) implementation, including support of pack(show) (useful for testing). - Implements support for named pack records which gcc seems to ignore (or implements incorrectly). - Not currently wired to anything, only functionality change is the type checking of the pragma. llvm-svn: 57476
