Plan: add a note in DXIL.rst that sdiv divide by zero behavior is undefined.
@llvm-beanz to see if this is something we need to address in clang. We aren't expecting to fix this in dxc.

This proposal describes a plan to address this: https://github.com/microsoft/hlsl-specs/pull/499
See https://devblogs.microsoft.com/directx/shader-model-6-9-and-the-future-of-cooperative-vector/
Need to update description to what needs to be done here so we can estimate this.
Moved to Dormant - we'd happily review a PR that adds support for this, but we're not planning on adding it to DXC.
It's not entirely clear that this is something that is likely to impact real-life scenarios. Until we have data otherwise, setting this to dormant.
Looks like some changes to SPIRV-Tools have snuck in again.
@jeffnn - is this something we still need to track?
