This change is breaking internal builds. We use the -Xfoo pattern but can
now no longer manage whether we allow an unused -Xfoo option to pass as a
warning or promote it to an error.

This reverts commit 98615fd376cea15af21e120e0e3ffa5ba68c2b6d <https://reviews.llvm.org/rG98615fd376cea15af21e120e0e3ffa5ba68c2b6d>.
