[LLVM] Infinite loop during LLVM InstructionCombining pass optimization
If you're able to reproduce the infinite loop with -O3 then you should
be able to dump out the IR that causes `opt -instcombine` to infloop,
unless the bug is truly esoteric (e.g. only caused by a specific
use-list ordering). Maybe take a closer look at the output from `opt
-print-before-all -O3`?
Alternatively you can use bugpoint to minimize the IR to get a small
reproducer that causes
