There's less breakage than expected. From the buildbot failures:
- llvm-clang-ubuntu-x-aarch64-pauth: Kaleidoscope fails with an assertion failure, orcv2 tests look for the x86-64 target (which is not built). Not sure what's going on here, cc @lhames. Workaround: temporarily require x86-registered-target
- clang-armv8-quick, clang-armv7-global-isel: orcv2-cbindings-lazy.test is unsupported on armv8l/s390x; supported targets should be listed explicitly.
- sanitizer-aarch64-linux-bootstrap-hwasan: test/Examples/IRTransforms/SimplifyCFG/* Fix: mark as unsupported if plugins are unavailable
- sanitizer-x86_64-linux-android, reverse-iteration seem spurious/unrelated to this patch.

I fixed these with #172140, as the changes seemed simple enough.
