        <pre>Currently target.experimental.use-modern-type-lookup is defaulted to off.

There are several reasons it should be on:

 - ExternalASTMerger is shared code which will allow other clients to complete
types from multiple sources, as LLDB does.

 - This will allow us to remove the ClangASTImporter, a large container of
state which can go bad over time.

 - ExternalASTMerger has much more complete unit testing; I believe the
remaining testsuite failures are because of as-yet-incomplete LLDB use of it.

It's possible to run the testsuite with use-modern-type-lookup enabled, by
changing g_experimental_properties in Target.cpp to make it default-on.  The
resulting testsuite failures need to be fixed and the setting should then be
enabled.</pre>
