radv: enable conditional discard optimisation on radv.
This fixes a bunch of GPU hangs introduced in some CTS
tests like
dEQP-VK.memory.pipeline_barrier.host_write_uniform_buffer.65536
It works around an issue seen in the LLVM backend, but
also makes the radv code work more like the radeonsi stack.
