disabled in NDEBUG builds). The option applies only to -cc1 invocations and is:

Check in the beginnings of my new vtable layout builder idea.

Right now, it's off by default but can be tested by passing -fdump-vtable-layouts to clang -cc1. This option will cause all vtables that will normally be emitted as part of codegen to also be dumped using the new layout code.

I've also added a very simple new vtable layout test case.

Introduce serialization and deserialization of diagnostic information
so that CIndex can report diagnostics through the normal mechanisms
even when executing Clang in a separate process. This applies both
when performing code completion and when using ASTs as an intermediary
for clang_createTranslationUnitFromSourceFile().

The serialized format is not perfect at the moment, because it does
not encapsulate macro-instantiation information. Instead, it maps all
source locations back to the instantiation location. However, it does
maintain source-range and fix-it information. To get perfect fidelity
from the serialized format would require serializing a large chunk of
the source manager; at present, it isn't clear if this code will live
long enough for that to matter.
