622fd4d061 r300/compiler: Implement simple loop emulation 
The loop emulation unrolls loops as may times as possbile while still
keeping the shader program below the maximum instruction limit.  At this
point, there are no checks for constant conditionals.  This is only enabled
for fragment shaders.

Eric Anholt
27bc2de546 i965: Use the state base address to avoid relocations. 
This makes the binding table code simpler, and is required for gen6,
which requires binding table addresses to be under 64k offset from the
surface state base addr.

No significant change in performance on firefox-talos-gfx.

178414eba4 i965: Remove caching of surface state objects. 
It turns out that computing a 56 byte key to look up a 20-byte object
out of a hash table was some sort of a bad idea.  Whoops.

before:
[ # ]  backend                         test   min(s) median(s) stddev. count
[  0]       gl            firefox-talos-gfx   37.799   38.203   0.39%    6/6
after:
[  0]       gl            firefox-talos-gfx   34.761   34.784   0.17%    5/6

73de09f265 i965: Convert the binding table to streamed indirect state. 
This slightly reduces reduces cairo-gl firefox-talos-gfx runtime on my
Ironlake:
before:
[ # ]  backend                         test   min(s) median(s) stddev. count
[  0]       gl            firefox-talos-gfx   38.236   38.383   0.43%    5/6
after:
[  0]       gl            firefox-talos-gfx   37.799   38.203   0.39%    6/6

It turns out the cost of caching these objects and looking them up in
the cache again is greater than the cost of just computing the object
again, particularly when the overhead of having a separate BO to pin
is removed.

(Those that are paying close attention will note that this is a
reversal of the path I was moving the driver in a couple of years ago.
The major thing that has changed is that back then all state was
recomputed when we wrapped the streaming state buffer, including
recompiling our precious programs.  Now, we're uncaching just the
objects that are cheap to compute, and retaining caching of expensive
objects)

118a47623a i965: Split constant buffer setup from its surface state/binding state.

f5bb775fd1 i965: Set the CC VP state immediately on state change. 
The cache lookup of these two little floats was .12% of total CPU time
on firefox-talos-gfx because we did it any time commonly-changed state
changed.  On the other hand, updating the CC VP bo immediately whenver
CC VP state changes is a .07% overhead due to putting a driver hoook
in glEnable().

3b3278519a i965: Move no_batch_wrap assertion out across the area we're trying to verify. 
It's more likely that we wrap badly in state setup than in the little
primitive packet.

ebed500fae st/egl: Do not build non-working driver combinations. 
The KMS backend requires a hardware pipe driver.  Do not build
egl_kms_swrast.  Also, only build egl_fbdev_swrast for fbdev backend.
It is a pure software backend.

extension, and is kept simple by only exporting the current mode.
