freedreno/a3xx: fd3_util -> fd3_format
All the "util" helpers are actually format-related

freedreno/a3xx: stencil fixes
For mem->gmem we don't sample depth/stencil as it's native type. So we
need to setup the swizzle state for the sampler based on the format used
for sampling.

freedreno/a3xx: alpha-test
Needed by some games, like etuxracer and supertuxkart which use alpha
test rather than blending, to handle texture transparency.

freedreno: gmem bypass
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.

freedreno: add a3xx support
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.
