Right now the ClangImporter relies on Sema to synthesize typealiases in some cases, which doesn't work if a Sema instance is not available, for example when the ClangImporter is asked to import a declaration while deserializing SIL during optimization. Begin addressing this by synthesizing typealiases for the following conformances: - ExpressibleByArrayLiteral.ArrayLiteralElement while importing OptionSets. - RawRepresentable.RawValue while importing raw-valued enums. - ObjectiveCBridgeable._ObjectiveCType while importing bridged newtypes. Until further changes land, this is mostly NFC, except for a change in generated interface printing where the new typealiases are now explicitly shown. Note that non-bridged newtypes whose raw type is ObjectiveCBridgeable still rely on associated type inference, because the ClangImporter cannot safely "copy" the _ObjectiveCType typealias from the raw type to the newtype, for various reasons mostly having to do with circularity. Subsequent patches will address this, in a rather novel fashion that will shock you.
