Revert of [intl] Remove redundant type checking system

Revert of [intl] Remove redundant type checking system (patchset #3 id:40001 of https://codereview.chromium.org/2591203002/ )

Reason for revert:
Issue https://bugs.chromium.org/p/chromium/issues/detail?id=677055 . I'll send out a follow-on reland, as it should still be possible to eliminate the redundant type system.
