For MTL (verx10 == 125), float64 is supported, but int64 is not. Therefore we need to lower cluster broadcast using 32-bit int ops. For gfx12.5+ platforms that support int64, the register regions used by cluster broadcast aren't supported by the 64-bit pipeline. On MTL, dEQP-VK.subgroups.clustered.*_double* and dEQP-VK.subgroups.clustered.*_dvec* were failing to validate the compiled shader in debug mode, and reportedly gpu-hanging in release mode. With this change dEQP-VK.subgroups.clustered.*_double* passed all 48 tests and dEQP-VK.subgroups.clustered.*_dvec* passed all 140 tests on MTL. Rework: * Move from generator to brw_fs_lower_regioning.cpp. (Suggested by Francisco) * Apply to verx10 >= 125..
