8231b3a750 [IRGen & Runtime] Remove prefab'ed VWT for reference storage types 
The prefab'ed value witness tables for reference storage types are a
premature optimization. Not all scenarios are covered, and those that
are "look suspect" according to John McCall.

98ee6a5d7d Runtime: Prefab metadata records for Any and AnyObject. 
Metadata for these types gets demanded fairly frequently, and it's a decent code size savings not having to emit a runtime call to access them.

5e80555c9b demangler: put the demangler into a separate library 
Previously it was part of swiftBasic.

The demangler library does not depend on llvm (except some header-only utilities like StringRef). Putting it into its own library makes sure that no llvm stuff will be linked into clients which use the demangler library.

This change also contains other refactoring, like moving demangler code into different files. This makes it easier to remove the old demangler from the runtime library when we switch to the new symbol mangling.

Also in this commit: remove some unused API functions from the demangler Context.
