was visited and all decls have been merged.

We only get a single chance to emit the types for virtual classes because
CGDebugInfo::completeRequiredType() categorically doesn't complete them.

Module Debugging: Use the clang module signature as the module's dwo_id
when building a module. Clang already records the module signature when
building a skeleton CU to reference a clang module.

Matching the id in the skeleton with the one in the module allows a DWARF
consumer to verify that they found the correct version of the module
without them needing to know about the clang module format.

Add a -gmodules option to the driver and a -dwarf-ext-refs to cc1
to enable the use of external type references in the debug info
(a.k.a. module debugging).

The driver expands -gmodules to "-g -fmodule-format=obj -dwarf-ext-refs"
and passes that to cc1. All this does at the moment is set a flag
codegenopts.

After r244870 flush() will only compare two null pointers and return,
doing nothing but wasting run time. The call is not required any more
