Remove the -cxx-abi command-line flag. This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples, Itanium otherwise. It's no longer possible to do weird combinations. To be able to run a test with a specific ABI without constraining it to a specific triple, new substitutions are added to lit: %itanium_abi_triple and %ms_abi_triple can be used to get the current target triple adjusted to the desired ABI. For example, if the test suite is running with the i686-pc-win32 target, %itanium_abi_triple will expand to i686-pc-mingw32.

CodeGen: __uuidof should work even with an incomplete _GUID type Summary: We would crash in CodeGen::CodeGenModule::EmitUuidofInitializer because our attempt to enter CodeGen::CodeGenModule::EmitConstantValue will be foiled: the type of the constant value is incomplete. Instead, create an unnamed type with the proper layout on all platforms. Punt the problem of wrongly defined struct _GUID types to the user.
