--- Comment #1 from Francisco Jerez <currojerez at riseup.net> ---
I see what's going on.  Apparently the SHUFFLE virtual instruction used by
Vulkan 1.1 subgroups operations doesn't behave correctly when its sources are
aligned in a way that complies with the CHV/BXT restrictions for
double-precision datatypes, and it's going to have to be special-cased in the
regioning lowering pass.

Mark, is there some way I can force the CI to run on these "slow" platforms
when I foresee potential regressions, so this doesn't happen again in the
future?
