swr: Correct texture allocation and limit max size to 2GB

This patch fixes piglit tex3d-maxsize by correcting 4 things:

The total_size calculation was using 32-bit math, therefore a >4GB
allocation request overflowed and was not returning false (unsupported).

Changed AlignedMalloc arguments from "unsigned int" to size_t, to handle
>4GB allocations.

Added error checking on texture allocations to fail gracefully.

Finally, temporarily decreased supported max texture size from 4GB to 2GB.
The gallivm texture-sampler needs some additional work to correctly handle
larger than 2GB textures (offsets to LLVMBuildGEP are signed).

I'm working on a follow-on patch to allow up to 4GB textures, as this is
useful in HPC visualization applications.

Fixes piglit tex3d-maxsize.

v2: Updated patch description to clarify ">4GB".

gallivm: fix texture wrapping for texture gather for mirror modes

Care must be taken that all coords end up correct, the tests are very
sensitive that everything is correctly rounded. This doesn't matter
for bilinear filter (since picking a wrong texel with weight zero is
ok), and we could also switch the per-sample coords mistakenly.
While here, also optimize the coord_mirror helper a bit (we can do the
mirroring directly by exploiting float rounding, no need for fixing up
odd/even manually).
I did not touch the mirror_clamp and mirror_clamp_to_border modes.
In contrast to mirror_clamp_to_edge and mirror_repeat these are legacy
modes. They are specified against old gl rules, which actually does
the mirroring not per sample (so you get swapped order if the coord
is in the mirrored section). I think the idea though is that they should
follow the respecified mirror_clamp_to_edge rules so the order would be
correct.

This rewires the logic for assigning uniform locations to work in terms
of "complex alignments".  The basic idea is that, as we walk the list of
instructions, we keep track of the alignment and continuity requirements
of each slot and assert that the alignments all match up.  We then use
those alignments in the compaction stage to ensure that everything gets
placed at a properly aligned register.  The old mechanism handled
alignments by special-casing each of the bit sizes and placing 64-bit
values first followed by 32-bit values.

The old scheme had the advantage of never leaving a hole since all the
64-bit values could be tightly packed and so could the 32-bit values.
However, the new scheme has no type size special cases so it handles not
only 32 and 64-bit types but should gracefully extend to 16 and 8-bit
types as the need arises.

intel/cfg: Represent divergent control flow paths caused by non-uniform loop execution.

This addresses a long-standing back-end compiler bug that could lead
to cross-channel data corruption in loops executed non-uniformly.  In
some cases live variables extending through a loop divergence point
(e.g. a non-uniform break) into a convergence point (e.g. the end of
the loop) wouldn't be considered live along all physical control flow
paths the SIMD thread could possibly have taken in between due to some
channels remaining in the loop for additional iterations.

This patch fixes the problem by extending the CFG with physical edges
that don't exist in the idealized non-vectorized program, but
represent valid control flow paths the SIMD EU may take due to the
divergence of logical threads.  This makes sense because the i965 IR
is explicitly SIMD, and it's not uncommon for instructions to have an
influence on neighboring channels (e.g. a force_writemask_all header
setup), so the behavior of the SIMD thread as a whole needs to be
considered.

intel/fs: Restrict live intervals to the subset possibly reachable from any definition.

Currently the liveness analysis pass would extend a live interval up
to the top of the program when no unconditional and complete
definition of the variable is found that dominates all of its uses.

This can lead to a serious performance problem in shaders containing
many partial writes, like scalar arithmetic, FP64 and soon FP16
operations.  The number of oversize live intervals in such workloads
can cause the compilation time of the shader to explode because of the
worse than quadratic behavior of the register allocator and scheduler
when running out of registers, and it can also cause the running time
of the shader to explode due to the amount of spilling it leads to,
which is orders of magnitude slower than GRF memory.

This patch fixes it by computing the intersection of our current live
intervals with the subset of the program that can possibly be reached
from any definition of the variable.  Extending the storage allocation
of the variable beyond that is pretty useless because its value is
guaranteed to be undefined at a point that cannot be reached from any
definition.

According to Jason, this improves performance of the subgroup Vulkan

intel/fs: Implement GRF bank conflict mitigation pass.

Unnecessary GRF bank conflicts increase the issue time of ternary
instructions (the overwhelmingly most common of which is MAD) by
roughly 50%, leading to reduced ALU throughput.  This pass attempts to
minimize the number of bank conflicts by rearranging the layout of the
GRF space post-register allocation.  It's in general not possible to
eliminate all of them without introducing extra copies, which are
typically more expensive than the bank conflict itself.

In a shader-db run on SKL this helps roughly 46k shaders:

   total conflicts in shared programs: 1008981 -> 600461 (-40.49%)
   conflicts in affected programs: 816222 -> 407702 (-50.05%)

The running time of shader-db itself on SKL seems to be increased by
roughly 2.52%±1.13% with n=20 due to the additional work done by the
compiler back-end.

On earlier generations the pass is somewhat less effective in relative
terms because the hardware incurs a bank conflict anytime the last two
sources of the instruction are duplicate (e.g. while trying to square
a value using MAD), which is impossible to avoid without introducing
copies.  E.g. for a shader-db run on SNB:

   total conflicts in shared programs: 944636 -> 623185 (-34.03%)
   conflicts in affected programs: 853258 -> 531807 (-37.67%)
   helped: 31052
   HURT: 19

And on BDW:

   total conflicts in shared programs: 1418393 -> 987539 (-30.38%)
   conflicts in affected programs: 1179787 -> 748933 (-36.52%)
   helped: 47592
   HURT: 70

On SKL GT4e this improves performance of GpuTest Volplosion by 3.64%
±0.33% with n=16.

NOTE: This patch intentionally disregards some i965 coding conventions
      for the sake of reviewability.  This is addressed by the next
      squash patch which introduces an amount of (for the most part

      non-trivial algorithmic details of the pass.
