And remove non-working code for indirect sampler/resource selection.
Will be added back later.
Includes code from "nv50/ir/tgsi: Resource indirect indexing" by
Francisco Jerez (when mixing the R and S handles we can only specify
them via a register, i.e. indirectly, unless we upload all the used
handle combinations to c[] space, which we don't for now).
Squashed and (heavily) modified original patches by Francisco Jerez:
nv50/ir/tgsi: Implement resource LOAD/STORE (wip).
nv50/ir/tgsi: Emit SUST/SULD for surface access, and add CB LOAD/STORE support
nv50/ir/tgsi: Fix/clean up the LOAD/STORE handling code.
Left out for now:
nv50/ir/tgsi: Resource indirect indexing
Treating raw, read-only surfaces as constant buffers (CBs) was removed
because CBs are limited to a size of 64 KiB which isn't desireable, and
because this decision should probably be made by the state tracker.
If we used a number of CB slots for surfaces, it might find that we
cannot accomodate the advertised limit.
OpenGL is nice and makes the user specify a format with an image unit.
OpenCL is evil and doesn't, and what's better than adding a huge load
of functions that we call indirectly to handle the conversion ?
A live range [0, 0) counts as empty. For function inputs this can
be a problem, so insert a nop at the beginning to make it [0, 1).
This is a bit of a hack but also the most simple solution.
Fixes mixing enum types defects reported by Coverity.

Currently works on a220. Others in the a2xx family look pretty similar
and should be pretty straightforward to support with the same driver.
The a3xx has a new shader ISA, and while many registers appear similar,
the register addresses have been completely shuffled around. I am not
sure yet whether it is best to support with the same driver, but
different compiler, or whether it should be split into a different
driver.
v1: original
v2: build file updates from review comments, and remove GPL licensed
header files from msm kernel
v3: smarter temp/pred register assignment, fix clear and depth/stencil
format issues, resource_transfer fixes, scissor fixes

Previously, the derivatives were calculated and passed in a packed form
to the sample code (for implicit derivatives, explicit derivatives were
packed to the same format).
There's several reasons why this wasn't such a good idea:
1) the derivatives may not even be needed (not as bad as it sounds since
llvm will just throw the calculations needed for them away but still)
2) the special packing format really shouldn't be part of the sampler
interface
3) depending what the sample code actually does the derivatives will
be processed differently, hence there is no "ideal" packing. For cube
maps with explicit derivatives (which we don't do yet) for instance the
packing looked downright useless, and for non-isotropic filtering we'd
need different calculations too.
So, instead just pass the derivatives as is (for explicit derivatives),
or let the rho calculating sample code calculate them itself. This still
does exactly the same packing stuff for implicit derivatives for now,
though explicit ones are handled in a more straightforward manner (quick
estimates show performance should be quite similar, though it is much
easier to follow and also does the rho calculation per-pixel until the
end, which we eventually need for spec compliance anyway).
No piglit changes.
