Move vtable type metadata emission behind a cc1-level flag. In ThinLTO mode, type metadata will require the module to be written as a multi-module bitcode file, which is currently incompatible with the Darwin linker. It is also useful to be able to enable or disable multi-module bitcode for testing purposes. This introduces a cc1-level flag, -f{,no-}lto-unit, which is used by the driver to enable multi-module bitcode on all but Darwin+ThinLTO, and can also be used to enable/disable the feature manually.
