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

Move unnamed_addr after the function arguments on Sabre's request. llvm-svn: 124210

Perform two more constructor/destructor code-size optimizations: 1) emit base destructors as aliases to their unique base class destructors under some careful conditions. This is enabled for the same targets that can support complete-to-base aliases, i.e. not darwin. 2) Emit non-variadic complete constructors for classes with no virtual bases as calls to the base constructor. This is enabled on all targets and in theory can trigger in situations that the alias optimization can't (mostly involving virtual bases, mostly not yet supported). These are bundled together because I didn't think it worthwhile to split them, not because they really need to be. llvm-svn: 96842

Revert the ctor/dtor alias optimization for now; the buildbots can detect some failure here that I can't. llvm-svn: 96612

Ensure that default arguments are handled correctly in sub scopes. For example: void f () { int g (int a, int b=4); { int g(int a, int b=5); } } should compile. llvm-svn: 152621
