i965/fs: Make virtual grf live intervals actually cover their used range.
Previously, we would sometimes not consider a write to a register to
extend the end of the interval, nor would we consider a read before a
write to extend the start. This made for a bunch of complicated logic
related to how to treat the results when dead code might be present.
Instead, just extend the interval and fix dead code elimination to know
how to remove it.
Interestingly, this actually results in a tiny bit more optimization:
total instructions in shared programs: 1391220 -> 1390799 (-0.03%)
instructions in affected programs: 14037 -> 13616 (-3.00%)
v2: Fix a theoretical problem with the simd16 workaround if dst == src,
where we would revert the bump of the live range.

Now tells Gallium that ilo supports primitive restart.
Updated ilo_draw_vbo to be able to check that the indexed
primitive being rendered can actually be supported in HW. If not,
will break up into individual prims similar to what Mesa does.
[olv: a minor fix after rebasing and formatting]
st/mesa: generate GL_OUT_OF_MEMORY if we can't create the index buffer
Before, if we failed to allocate the index buffer we'd silently
return from st_draw_vbo() without drawing anything. We should
raise GL_OUT_OF_MEMORY to give some indication that something went
wrong.
Note: This is a candidate for the stable branches.

It helps a bit with vertex shader performance on i915g
(a couple percent faster with openarena).
I have tried most other passes, and they weren't showing
any measurable improvement. Note that my vertex shaders
didn't have loops, so maybe the loop optimizations could
still be useful in the future.

This basically reverts commit
2acc719374.
With the previous change, we're not batchbuffer limited any
longer. So we actually start seeing a performance difference
between X and Y tiling. X tiling is funny because it is
faster for screen-aligned quads but slower in games. So let's
use Y tiling which is 10% faster overall.
Now that we don't throttle at every batchbuffer, we can shrink
the size of batchbuffers to achieve early flushing. This gives
a significant speed boost in a lot of games (on the order of
20%).
It should be TGSI_TYPE_UNSIGNED, not TGSI_TYPE_FLOAT.
Fixed also gallivm not_emit_cpu() to use uint build context.

Make use of tgsi_util_get_texture_coord_dim() to replace the big switch table.
There is a subtle difference with this change. When TXP is used with an array
texture, the layer is now also projected. This behavior matches the TGSI doc.
Since GLSL does not allow TXP on an array texture, I am not sure which
behavior is correct or preferred.

This util function returns the dimension of the texture coordinates for a
texture target, and the location of the shadow reference value.
For example, when the texture target is TGSI_TEXTURE_SHADOW2D, the dimension
of the texture coordinates is 2, and the location of the ref value is 2
(that is, the Z channel).

r600g/sb: optimize some cases for CNDxx instructions
We can replace CNDxx with MOV (and possibly eliminate after
propagation) in following cases:
If src1 is equal to src2 in CNDxx instruction then the result doesn't
depend on condition and we can replace the instruction with
"MOV dst, src1".
If src0 is const then we can evaluate the condition at compile time and
also replace it with MOV.

Use the same limit for kcache constants in alu group on r6xx as on other
chips (two const pairs). Relaxing this will require additional checks to
make sure that all 4 consts in the group come from 2 kcache sets (clause
limit), probably without noticeable improvements of shader performance.

mesa: Make Mesa core set up wrapped texture renderbuffer state.
Everyone was doing effectively the same thing, except for some funky code
reuse in Intel, and swrast mistakenly recomputing _BaseFormat instead of
using the texture's _BaseFormat. swrast's sRGB handling is left in place,
though it should be done by using _mesa_get_render_format() at render time
instead (as-is, it will miss updates to GL_FRAMEBUFFER_SRGB).
