Barriers execute on the texture pipeline on Midgard, so let's
tentatively handle barrier() as conservatively as possible (forcing
memory barriers of both buffers and shared memory). Implementation isn't
quite there yet -- it doesn't look at interactions of adjacent barriers
like it's supposed to -- but the core is there.

These structures are the norm on midgard t760+, drop the bifrost names,

It's a complicated story. But from what I can tell, in GL compute
without barriers, the blob is able to redistribute the workgroups in
various ways (that are not yet understood), whereas with barriers it
cannot redistribute anything, which accounts for erratic workgroup
packing without barriers.

We discovered 2 new shader flags used when a fragment shader updates
the depth/stencil value through a ZS writeout. If those flags are not
set, the depth/stencil value stored in the depth/stencil tilebuffer
remain unchanged.
While at it, rename unknown2 into flags_hi and rename flags into
flags_lo.

Midgard can't write depth and stencil separately. It has to happen in
a single store operation containing both. Let's add a panfrost specific
intrinsic and turn all depth/stencil stores into a packed depth+stencil
one.
Note that this intrinsic is not yet handled in emit_intrinsic(), but
we'll address that later.

nir_intrinsic_base() is assigned nir_variable.data.driver_location,
which is assigned a unique ID based on the variable position in the
shader variable list. There's no guarantee that this position will
match the RT id we want to pass to emit_fragment_store().
Add a search_var() helper to retrieve a nir_variable based on its driver
location, so we can pass the right RT value to emit_fragment_store().
We also make sure the shader output is color, since emit_fragment_store()
is not ready for depth/stencil stores yet.
