Bob Haarman dff36738d1 [codeview] emit debug info for indirect virtual base classes 
Summary:
Fixes PR28281.

MSVC lists indirect virtual base classes in the field list of a class.
This change makes Clang emit the information necessary for LLVM to
emit such records.

Reid Kleckner 598124296b [codeview] Don't emit vshape info for classes without vfptrs 
Classes with no virtual methods or whose virtual methods were all
inherited from virtual bases don't have a vfptr at offset zero. We were
crashing attempting to get the layout of that non-existent vftable.

We don't need any vshape info in this case because the debugger can
infer it from the base class information. The current class may not
introduce any virtual methods if we are in this situation.
