Yes, yesterday I added this configuration to our bootstrap bot (
http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-bootstrap), but
Clang failed to build with ubsan there due to reported error in tablegen.
I'll investigate this and create a bug when Clang successfully
builds and runs the test suite.
