rABC7e560769acbe: [CI] Enable the undefined behaviour sanitizer

This diff enables UBSAN build.
It requires running with clang as UBSAN support in gcc is very poor (at
least until most recent versions ; in particular it won't run on Debian
9 which is our current CI target).

Test Plan

Run the CI build-ubsan config.

It's probably preferable to run them together and have 2 builds instead, no?

Fabien updated this revision to Diff 10615.Mon, Aug 5, 16:41

Separate build-ubsan from build-asan.
