Reland "[clang] Add experimental option to omit the RTTI component from the vtable when -fno-rtti is used"
This reverts commit 070493ddbd9473499d6f00ca62bc6aa92808ed79 (and
relands the original change). This removes a test run that makes an
assumption of RTTI being on by default for a given target.
