--- Comment #1 from max.kazantsev at azul.com ---
This issue has been resolved with following patches:

https://reviews.llvm.org/D29071
https://reviews.llvm.org/D29378

We changed the approach to canonicalization, preferring merging adjacent guards
rather than splitting them. This allows us to reduce the size of generated
code.
