This warning is designed to be an early report of name conflicts in swiftinterfaces caused by a type having the same name as a module. Make sure we silence this warning when the workaround -alias-module-names-in-module-interface is enabled. This is what we already do for -module-interface-preserve-types-as-written. rdar://132990400
