The fossil-db results are very different from v1. This is now mostly helpful on older platforms. v2: When optimizing BROADCAST or FIND_LIVE_CHANNEL to a simple MOV, adjust the exec_size to match the size allocated for the destination register. Fixes EU validation failures in some piglit OpenCL tests (e.g., atomic_add-global-return.cl). v3: Use component_size() in emit_uniformize and BROADCAST to properly account for UQ vs UD destination. This doesn't matter for emit_uniformize because the type is always UD, but it is technically more correct. v4: Update trace checksums. Now amly expects the same checksum as several other platforms. v5: Use xbld.dispatch_width() in the builder for when scalar_group() eventually becomes SIMD1.
