Instead of requiring an explicit unoptimized move, we can implicitly
colour the blend input intrinsic to r0, where it will be preloaded; this
is a simple task for RA, and does not conflict with anything. If there
are multiple duplicate loads, the latter ones can just be simple moves
which will be copypropped.
We don't need to include a explicit synthetic load, since (scanning
backwards) the read will cause the input to become live at the right
time and the lack of an explicit write will keep it live from the
beginning of the shader. So no need to make it more complicated than it
needs to be.
Saves a cycle in blend shaders.

This uses the new nir_intrinsic_store_combined_output_pan intrinsic,
which can write depth, stencil and color in a single instruction. If
there are no color writes, the "depth RT" is written to.
Fixes the dEQP GLES3 depth write tests, as well as the piglit tests
fragdepth_gles2, glsl-1.10-fragdepth and when modified to not rely
on depth/stencil reload, glsl-fs-shader-stencil-export.

We schedule depth writeout to smul and stencil to vlut, so scheduling
to smul has to be disabled in these cases.
When only writing stencil, scheduling to smul is still disabled to
prevent stencil writeout from being scheduled there.

By setting the swizzle for the fragment color, and setting qmask to ~0
for branches, the special case for writeout branches can be removed
from mir_bytemask_of_read_components_index.

We need to be able to do color writeout at the same time as depth
writeout. The old code can't do that, so needs to be removed.

It is broken for when there are also color writes, and will be
replaced with a new lowering which takes that into account.

There will need to be sources for depth and stencil writeout, so
something has to be moved to the dest of the writeout branch.

Since these shaders are purely internal, the optimization criteria are a
bit different, so it's worth calling attention to this when dumping.
