[lldb][NFC] Move LLVM RTTI implementation from enum to static ID variable

Authored by teemperor on Nov 11 2019, 2:13 AM.



swift-lldb currently has to patch the ExpressionKind enum to add support for Swift expressions. If we implement LLVM's RTTI
with a static ID variable instead of a centralised enum we can drop that patch.

Swift aside, I think it's also good that the generic Expression class does not need to know about the various kinds of expressions that the Clang Expression parser plugin wants to invent.
