After some more investigation, you're right.
However, there is some SI-specific bug that none of D60459 <https://reviews.llvm.org/D60459>, D61313 <https://reviews.llvm.org/D61313>, and D60457 <https://reviews.llvm.org/D60457> fix. It's triggered by a trivial modification of an unfortunately relatively complex shader and is extremely sensitive to code changes, so it might be some missing hazard or similar. I'll have to investigate that further.
