6d63f12d - [InstCombine] Propagate poison through fshl and fshr intrinsics (#172859)

[InstCombine] Propagate poison through fshl and fshr intrinsics (#172859) Currently these intrinsics output `undef` on poison, which triggers CI errors on PRs that want to add poison tests for funnel shifts (such as #172723). Let's make `fshl` and `fshr` propagate poison instead.
