Hi all,
After a recent upstream merge into our downstream sources we are
suddenly encountering the freeze instruction in LLVM IR for div/rem
pairs. This seems to be related to [1].
Our downstream target is GlobalISel only and unfortunately GlobalISel
doesn't support this instruction yet, so most of our internal test-suite
