Now that all scratch contexts are using precise per-CU compiler invocations, the infrastructure for the per-module fallback scratch context is no longer needed, since it is actually less precise than the "normal" contexts. This patch removes the notion of a fallback SwiftASTContext entirely.
This mechanism was put into place to deal with SwiftASTContexts being torn down and replaced. While that may still happen, we no have a much better solution for the problem of dangling type references: CompilerType now holds a weak_ptr to the type system so it's safe to destroy a type system.
