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.
When we look up the DRI drawable state we need to associate an fbconfig
with the drawable. With GLX_EXT_no_config_context we can no longer infer
that from the context and must instead query the server.

On CNL, we see multiple multisample failures on piglit tests. By
emitting this extra state, though not documented in the bspec, those
failures seem to go away.
This workaround could be removed if we ever find out a better solution,
but it should be good enough for now.
