[PATCH] D89392: [GlobalISel] Fold unary opcodes in CSEMIRBuilder

[Dominik Montada via Phabricator via llvm-commits]

I just tested the patch in our downstream implementation. While it doesn't cause any infinite loops in our regression tests, it seems to have caused our build bots to crash. I cannot attribute this 100% to this patch though. The crash reason is reported as running out of disk space, but checking all agents still have hundreds of gigs of free space, which is why I suspect that it ran out of memory due to the infinite loops instead. Especially since our nightly runs finished without any hick-ups just hours prior.

Unfortunately at the moment I cannot narrow this down further or even create a minimal example without some more time-consuming investigation.
