When the swiftmodule is built with different clang importer arguments, they can have the same module hash, causing them to be wrongly re-used even they contains different interfaces. Add ReducedExtraArgs to the module hash to disambiguate them. However, some Xcc arguments, most commonly `-D` options do not affect the swiftmodule being generated. Do not pass `-Xcc -DARGS` to swift interface compilation to reduce the amount of module variants in the build. rdar://131408266
