Introduce a debug info independent type, ImportedDeclaration, which is analogous to DWARF's DW_AT_imported_declaration, as well as a way to search them by name.
Types annotated with @_originallyDefinedIn don't live in the module listed in their mangled name. To account for this, the compiler emits a DW_TAG_imported_declaration for those types under the name of the swiftmodule these types can be found at. This patch implements the logic required to produce the mangled name that can be used in type reconstruction to successfully find these types. rdar://137146961
