Implement a better version of delegating constructor cycle detection.
...
This is more efficient as it's all done at once at the end of the TU.
This could still get expensive, so a flag is provided to disable it. As
an added bonus, the diagnostics will now print out a cycle.
The PCH test is XFAILed because we currently can't deal with a note
emitted in the header and I, being tired, see no other way to verify the
serialization of delegating constructors. We should probably address
this problem /somehow/ but no good solution comes to mind.

Synthesizing the definition of an implicit member is an AST modification, so notify any mutation listeners of it. This fixes a crasher in chained PCH, where an implicit destructor in a PCH gets a definition in a chained PCH, which is then lost. However, any further use of the destructor would cause its definition to be regenerated in the final file, hiding the bug.

On reading DeclContexts from PCH, check for visible updates even if the context was empty in the original version. Also, if there are any, tell the context that it has external visible decls. This fixes the problem that a namespace that was empty in the initial PCH (could also happen if the initial PCH didn't include any std header but caused implicit creation of namespace std, e.g. due to implicit declaration of a virtual destructor) never found any declaration declared in *any* chained PCH. Very ugly when the chained PCH includes all that std stuff, as the errors were effectively the same as not including std headers.

Store the full list of pending instantiations in a chained PCH. Previously we attempted to store only new pending instantiations, but our filter was incorrect, dropping implicit instantiations of class template members. It's just not worth coming up with a complex filter that is correct, when the only cost is PCH files that are a few hundred bytes (at most) larger.

altogether.

we would deserialize all of the macro definitions we knew about while

a performance problem.
Now, we do the standard AST/PCH chaining trick: watch what identifiers
are deserialized as macro names, and consider only those identifiers
(along with macro definitions that have been deserialized/written in
the source) when serializing the preprocessor state.
