We did downsample (=resolve) MSAA resources to make ReadPixels work with MSAA
GLX visuals, which was enough for read-only color-only transfers.
This commit makes write color transfers and depth-stencil transfers work
in a similar manner. It does downsampling in transfer_map and upsampling
in transfer_unmap.

There isn't any difference between 32_FLOAT and 32_*INT in vertex fetching.

There is really nothing in struct intel_bo, and having it alias drm_intel_bo
makes the winsys impose almost zero overhead.
We can make the overhead gone completely by making the functions static
inline, if needed.

Move functions around to match the order of the declarations in the header.

The motivation is to kill tiling and pitch in struct intel_bo. That requires
us to make tiling and pitch not queryable, and be passed around as function
parameters.

We are moving toward making struct intel_bo alias drm_intel_bo. As a first

Works similarly to clip distance. If the cull distance is negative
for all vertices against a specific plane then the primitive
is culled.

cull distance is analogous to clip distance. If a register is
given this semantic, then the values in it are assumed to be a
float32 distance to a plane. Primitives will be completely
discarded if the plane distance for all of the vertices in
the primitive are < 0.

We need to figure out the number of invocations of the clipper
before the emit, because in the emit we are after clipping
where the number of primitives will be equal to number of clipper
invocations minus the clipped primitives. So our computations
were always off by the number of clipped primitives.

Draw depended on clip_plane_enable being set in the rasterizer
to use clipdistance registers for clipping. That's really
unfriendly because it requires that rasterizer state to have
variants for every shader out there. Instead of depending on
the rasterizer lets extract the info from the available state:
if a shader writes clipdistance then we need to use it and we
need to clip using a number of planes equal to the number
of writen clipdistance components. This way clipdistances
just work.

draw_vertex_buffer declared the size field to be a size_t, but the LLVM
code used an int32 instead. This caused problems on big-endian 64-bit
targets, because the first 32-bit chunk of the 64-bit size_t was always 0.
In one sense size_t seems like a good choice for a size, so one fix
would have been to try to get the LLVM code to use the equivalent of
size_t too. However, in practice, the size is taken from things like ~0
or width0, both of which are int-sized, so it seemed simpler to make the
size field int-sized as well.

lp_build_add and lp_build_sub have fallback code for cases
that cannot be handled by known intrinsics. For UNORM formats,
this code was using modulo rather than saturating arithmetic.
This fixes some rendering issues for a gnome session on System z.
It also fixes various piglit tests on z, such as
spec/ARB_color_buffer_float/GL_RGBA8-render.
The patch deliberately doesn't tackle the more complicated
SNORM case.
Tested against piglit on x86_64 and System z with no regressions.

The GPU (at least a3xx, but I think also a2xx) can render directly to
memory, bypassing tiling. Although it can't do this if blend, depth,
and a few other features of the pipeline are enabled. This direct
memory mode can be faster for some sorts of operations, such as simple
blits. In particular, this significantly speeds up XA by avoiding to
pull the entire dest pixmap into GMEM, render tiles, and write it all
back out again. This should also speed up resource copy-region and
blit.

The adreno a3xx GPU is found in newer snapdragon devices, such as the
nexus4. The a3xx is GLESv3 and OpenCL capable, although that is not
enabled yet in gallium.
Compared to a2xx, it introduces an entirely new unified shader ISA, and
re-shuffles all or nearly all of the registers. The good news is that
(for the most part) the registers are more orthogonal, not combining
unrelated state in a single register. And that there is a lot more
flexibility, so we don't need to patch and re-emit the shader like we
did on a2xx.
The shader compiler is currently quite dumb, there would be a lot of
room for improvement with an optimizing pass. Despite that, with the
a320 in my nexus4 it seems to be ~2-3x faster compared to the a220 in my
HP touchpad.

We use 128bit vector interleave for untwiddling in the blend code (with
256bit vectors). llvm generates terrible code for this for some reason,
so instead of generating a shuffle for 2 128bit vectors use a
extract/insert shuffle instead (it only seems to matter we're not using
128bit wide vectors for the shuffle). This decreases instruction count of
the blend code generated for a rgba8 render target without blending from
169 to 113 with llvm 3.1 and from 136 to 114 in llvm 3.2/3.3, and I got
a ~8% (llvm 3.1) and ~5% (3.2/3.3) performance improvement in gears.
(The generated code is still not terribly good as we could actually avoid
the interleaving completely but llvm can't know this.)

Mostly just make sure the layer parameter gets passed through to the right
places (and get clamped, can do this at setup time), fix up clears to
clear all layers and disable opaque optimization. Luckily don't need to
touch the jitted code.
(Clears invoked via pipe's clear_render_target method will not work however
since the pipe_util_clear function used for it doesn't handle clearing
multiple layers yet.)
v2: per Brian's suggestion, prettify var initialization and add some comments,
add assertion for impossible layer specification for surface.

Transfers always use z/depth for layers no matter if it's a 1d or 2d array
