There is some remaining build issue on Windows. Will reproduce locally.

Windows failures were caused by windows-latest switching to VS 2026. I changed the build infrastructure to pin to windows-2022 (VS 2022).

However, LLVM introduced an arm-32 regression here: llvm/llvm-project#209244

correctness_interleave_rgb with target=host-hvx hit an LLVM assertion
(EVT::getSimpleVT: Expected a SimpleValueType) inside
HexagonTargetLowering::PerformHvxDAGCombine. CodeGen_Hexagon::interleave_vectors
routed 3-way interleaves of small boolean/predicate vectors (from
TailStrategy::GuardWithIf + unroll(c)) through the vdelta byte-shuffle network,
which assumes native-HVX-vector-sized byte data; the resulting sub-native,
padded/undef-laden shuffle chain trips a recent LLVM main regression in the
Hexagon backend's DAG combiner.

Cast boolean vectors to i8 before interleaving (mirroring vdelta's own
bool handling) and cast back afterward, avoiding the problematic pattern
entirely.
