I think this is wrong: `OpTypeRuntimeArray` requires `Shader` capability, but the triple makes this run for `Kernel`. @aadeshps-mcw can you please help me understand what are you trying to test here? If we change the triple to `spirv-unknown-vulkan-compute`, which would run for `Shader`, there is no `OpTypeRuntimeArray`, instead there is an `OpConstant`, which I assume comes from some optimization/pass. @Keenuts can you confirm?
