Previously, the best thing we had was to schedule the things unblocked by
the last chosen instruction, on the hope that it would be consuming two
values at the end of their live intervals while only producing one new
value. But that's just a guess, and we can do counting of usage of
registers to know when an instruction would (almost surely) reduce
register pressure.
The only failure mode I know of in this new dominant heuristic is that
inside of a loop when scheduling the iterator (for example), choosing the
last use of the iterator doesn't actually reduce the live interval of the
iterator. But it doesn't seem to matter in shader-db:
total instructions in shared programs: 1618700 -> 1618700 (0.00%)
instructions in affected programs: 0 -> 0
GAINED: 13
LOST: 0
Note: The new functions are made virtual because I expect we'll soon lift
the pre-regalloc scheduling heuristic over to the vec4 backend.

Otherwise, the function would enable generic vertex attributes 0
and 1 of the array object it does not own. This was causing crashes
in Euro Truck Simulator 2, since the incorrectly enabled generic
attribute 0 in the foreign context got precedence before vertex
position attribute at later time, leading to NULL pointer dereference.

Commit b16b3c87 began performing CSE on CMP instructions with null
destinations. I relaxed the restrictions a bit too much, thereby
allowing CSE to be performed on instructions with, for instance, an
explicit accumulator destination.
This broke the arb_gpu_shader5/fs-imulExtended shader tests because
they emit MUL instructions with the accumulator as the destination. CSE
would instead cause the MUL to write to a GRF, which is lower precision
than the accumulator.

These provide an interface between the driver and the loader to allocate
color buffers through the DRIimage extension interface rather than through a
loader-specific extension (as is used by DRI2, for instance).
The driver uses the loader 'getBuffers' interface to allocate color buffers.
The loader uses the createNewScreen2, createNewDrawable, createNewContext,
getAPIMask and createContextAttribs APIS (mostly shared with DRI2).
This interface will work with the DRI3 loader, and should also work with GBM
and other loaders so that drivers need not be customized for each new loader
interface, as long as they provide this image interface.
