Description
I don't have a AMD gpu that I can debug this on but something has broken with Int128 arrays in Julia 1.12.
This was found when testing a GPUArrays.jl PR that adds Int128 to the list of eltypes tested in the testsuite: https://buildkite.com/julialang/gpuarrays-dot-jl/builds/1828/canvas?sid=019f99ef-2d3f-4354-b5aa-41128d35a9f0

Research direction
Start by examining the GPUArrays.jl PR and the linked Buildkite run to reproduce the Int128 array failure on AMD GPU support with Julia 1.12. Trace the failing tests and identify the regression; done means Int128 arrays pass the relevant GPUArrays.jl tests again.
