I have a problem when writing a test. Clang doesn't implement Microsoft 
ABI and he crashes at code generation stage.
Clang have dump-record-layouts option but he prints AST layouts and 
CodeGen layouts.

Is there a way to save only AST record layout to file and then check
or maybe my patch must include CGRecordLayoutBuilder for Microsoft?

I`m working on CGRecordLayoutBuilder for Microsoft but I have problems 
with vbtables.
Itanium ABI doesn't have vbtables and Microsoft ABI doesn't have VTT. It 
is quite heavy task.
