i965/nir/fs: Implement new barrier functions for compute shaderscs-shader-barrier-funcs-v1
For these nir intrinsics, we emit the same code as
nir_intrinsic_memory_barrier:
* nir_intrinsic_memory_barrier_atomic_counter
* nir_intrinsic_memory_barrier_buffer
* nir_intrinsic_memory_barrier_image
We treat these nir intrinsics as no-ops:
* nir_intrinsic_group_memory_barrier
* nir_intrinsic_memory_barrier_shared
