Seems like in certain cases, we cannot use c<a0.x+0> as the third src to
cat3 instructions. This may be slightly conservative, we may only have
this restriction when the first src is also const.
This fixes, for example, +24/-0 of the variable-indexing piglit tests.

nir.h is a bit inconsistent about 'typedef struct {} nir_foo' vs
'typedef struct nir_foo {} nir_foo'. But missing struct name tags is
inconvenient when you need a fwd declaration without pulling in all
of nir.
So add missing struct name tag for nir_variable, and a couple other
spots where it would likely be useful.

The ARB has decided that implicit conversions should be performed for
bitwise operators in future language revisions. Implementations of
current language revisions may or may not perform them.
This patch makes Mesa apply implicti conversions even on current
language versions. Applications appear to expect this behavior,
and there's really no downside to doing so.

In the vertex and fragment stages, the hardware is nice to us and leaves
g0.2 zerod out for us so we can use it for headers. However, in compute,
geometry, and tessellation stages, the hardware is not so nice. In
particular, for compute shaders on BDW, the hardware places some debug bits
in 23:15. As it happens, bit 15 is interpreted by the sampler as the alpha
channel mask. This means that if you use a texturing instruction with a
header in a compute shader, you may randomly get the alpha channel
disabled. Since channel masks affect the return length of the sampler
message, this can lead the GPU to expect a different mlen to the one you
specified in the shader and this, in turn, hangs your GPU.

The cleaning up was quite a performance hog (making pipe_resource_reference
the number two in profilers on the vertex path, and 3rd overall, with its
cousin pipe_reference_described not far behind) if there were lots
of tiny draw calls (ipers). Now the reason was really that it was blindly
calling this for all potential shader views (so 32 each for vs and gs) even
though the app never touched a single one which could have been fixed,
however I can't come up with a good reason why we refcount these. We've got
references, of course, in the sampler views, which should be quite sufficient
as we do all vertex and geometry shader execution fully synchronous.
(Calling prepare_shader_sampling for all draw calls even if there were no
changes looks quite suboptimal too, but generally we don't really expect vs/gs
shader sampling to be used much with llvmpipe, and there's even an early exit
if there aren't any views to avoid the "null loop" albeit it's now no longer
always trying to loop through all 32 slots. Maybe improve another time...).
Of course, if we manage to make vertex loads run asynchronously some day,
we need references again, but adding that back would be the least of the
problems...
Also only set LP_NEW_SAMPLER_VIEW for fragment sampler views. Nothing on the
vertex side depends on it (I suppose we'd really wanted a separate flag in
any case).
(Good for a 3% improvement or so in ipers under the right conditions.)

This was not really a leak per se, but we were referencing the textures for
longer than intended. If textures were set via llvmpipe_set_sampler_views()
(for fs) and then picked up by lp_setup_set_fragment_sampler_views(), they
were referenced in the setup state. However, the only way to unreference them
was by replacing them with another texture, and not when the texture slot
was replaced with a NULL sampler view. (They were then further also referenced
by the scene too which might have additional minor side effects as we limit
the memory size which is allowed to be referenced by a scene in a rather crude
way.) Only setup destruction (at context destruction time) then finally would
get rid of the references.
Fix this by noting the number of textures the last time, and unreference
things if the new view is NULL (avoiding having to unreference things
always up to PIPE_MAX_SHADER_SAMPLER_VIEWS which would also have worked).

Only modify interpolation type for integer-based varyings or when the
consumer is known and different than fragment shader.
If we are linking separate shader programs and the consumer is unknown,
the consumer could be added later and be a fragment shader. If we
modify the interpolation type in this case, we could read wrong
values in the fragment shader inputs, as shown in bug 93320.

This will be used on Gen8+ to make sure that the color calculator
state pointers are re-emitted when switching back to the 3D pipeline
after some GPGPU workload due to a hardware workaround. There are
other state bits already defined that could be used to achieve the
same effect but they all cause a ton of unrelated state to be
re-emitted (e.g. BRW_NEW_STATE_BASE_ADDRESS), so just define a new
one, state bits are cheap.

Previously we were treating any indirect temp array usage to mean that
everything should end up in lmem. The MemoryOpt pass would clean a lot
of that up later, but in the meanwhile we would lose a lot of
opportunity for optimization.
This helps a lot of Metro 2033 Redux and a handful of KSP shaders:
total instructions in shared programs : 6288373 -> 6261517 (-0.43%)
total gprs used in shared programs : 944051 -> 945131 (0.11%)
total local used in shared programs : 54116 -> 54116 (0.00%)
A typical case is for register usage to double and for instructions to
halve. A future commit can also optimize local memory usage size to be
reduced with better packing.

Indirect constbuf indexing works by using very large offsets. However if
an indirect constbuf index load is const-propagated, it becomes a very
large const offset. Take that into account when legalizing the SSA by
moving the high parts of that offset into the file index. Also disallow
very large (or small) indices on most other instructions.
This fixes regressions in ubo_array_indexing/*-two-arrays piglit tests.

The OpenGL specifications for bitfieldExtract() says:
The result will be undefined if <offset> or <bits> is negative, or if
the sum of <offset> and <bits> is greater than the number of bits
used to store the operand.
Therefore passing bits=32, offset=0 is legal and defined in GLSL.
But the earlier SM5 ubfe/ibfe opcodes are specified to accept a bitfield width
ranging from 0-31. As such, Intel and AMD instructions read only the low 5 bits
of the width operand, making them not able to implement the GLSL-specified
behavior directly.
This commit adds ubfe/ibfe operations from SM5 and a lowering pass for
bitfield_extract to to handle the trivial case of <bits> = 32 as
