The gallium glsl->nir pass currently lowers away all indirects on both inputs
and outputs. This fuction allows us to lower vs inputs and fs outputs and also
lower things one stage at a time as we don't need to worry about indirects
on the other side of the shaders interface.

Because NIR can create non vec4 variables when implementing component
packing we need to make sure not to reprocess the same slot again.
Also we can drop the fs_attr_idx counter and just use driver_location.

We want to be able to generate NIR then apply NIR optimisations.
Once the optimisations are done we can then apply the new post opt

ctx->last_fence isn't such a terribly clever idea, if batches can be
flushed out of order. Instead, each batch now holds a fence, which is
created before the batch is flushed (useful for next patch), that later
gets populated after the batch is actually flushed.

In transfer_map(), when we need to flush batches that read from a

Instead of emitting absolutely everything, just emit the few functions
that are actually referenced in some way by the entrypoint. This should
save us quite a bit of time when handed large shader modules containing
many entrypoints.

Since almost all BOs will be in one CL at a time, this cache will almost
always hit except for the first usage of the BO in each CL.
This didn't show up as statistically significant on the minetest trace
(n=340), but if I lop off the throttled lobe of the bimodal distribution,
it very clearly does (0.74731% +/- 0.162093%, n=269).
No significant difference in the minetest replay, but it should reduce
overhead by not requiring that we write quad indices to index buffers that
we repeatedly re-upload (and making the draw packet smaller, as well).
Over the course of the series the actual game seems to be up by 1-2 fps.
Now that there's only one user of it, it's pretty obvious how to avoid
emitting redundant ones. This should save a bunch of kernel validation
overhead.
No statistically sigificant difference on the minetest trace I was looking
at (n=169), but the maximum FPS is up by .3%
Originally there was CL code for handling various relocations back when I
had relocs for the TSDA/TA buffers. Now that the kernel handles those
entirely on its own, I can inline that code into the one place using it.
We failed to take the start into account for how many vertices to draw in
this round, so we would end up decrementing count below 0, which as an
unsigned number meant we would loop until the CLs soon ran out of space.
When I wrote the code I was thinking about how to use the previously
emitted shader state (no index bias baked into the elements) by emitting
up to 65535 and then only re-emitting with bias for the second wround, but
that doesn't work if the start is over 65535. Instead, just delay
emitting shader state until we get into the drawarrays GFXH-515 loop and
always bake the bias in when we're doing the workaround.
They are the same thing, but this is more consistent with the rest of
the project.
