Thanks for reducing!
If I'm seeing it correctly, the codegen looks fine - the difference is in the IR icmp predicate changing from `slt` to `ult`, and that diff appears to be correct independent of whether or not we use the abs intrinsic:

So either the source/test has an incorrect expectation and/or something outside of this function is wrong?
