We should revert this patch. It breaks mupltiple bots, introducing Msan reports.

Also on a first look I don't like `-fsanitize-pattern-exclusion=` at all, very inconsistent.
I assumed we agreed to splitting sanitizers into smaller sets?
I would like to know why we need to introduce a new approach instead of using existing one.

Sorry, but I am not sure why this didn't show up my https://github.com/llvm/llvm-project/pulls?q=is%3Aopen+is%3Apr+review-requested%3A%40me+sort%3Aupdated-desc I wanted to review this patch.

@MaskRay maybe have opinion here as well?
