i965/vs: Rework binding table size calculation.
Unlike the FS, the VS backend already computed the binding table size.
However, it did so poorly: after compilation, it looked to see if any
pull constants/textures/UBOs were in use, and set num_surfaces to the
maximum surface index for that category. If the VS only used a single
texture or UBO, this overcounted by quite a bit.
The shader time surface was also noted at state upload time (during
drawing), not at compile time, which is inefficient. I believe it also
had an off by one error.
This patch computes it accurately, while also simplifying the code.
It also renames num_surfaces to binding_table_size, since num_surfaces
wasn't actually the number of surfaces used. For example, a VS that
used one UBO and no other surfaces would have set num_surfaces to
SURF_INDEX_VS_UBO(1) == 18, rather than 1. A bit of a misnomer there.

Even if that continues to be true, using the macro clarifies the code.
The comment about draw buffers needing to be first in order for

this change, SURF_INDEX_DRAW can be changed to arbitrary indices and
everything continues working.
The confusion was over the "Render Target Index" field in the FB write

i965/fs: Fully recompute liveout at each step.
Since we start with an overestimation of livein (0xffffffff), successive

i965/fs: Separate the updating of liveout/livein.
To compute the actual liveout/livein data flow values, we start with
some initial values and apply a fixed-point algorithm until they settle.
Previously, we iterated through all blocks, updating both liveout and
livein together in one pass. This is awkward, since computing livein
for a block requires knowing liveout for all parent blocks. Not all
of those parent blocks may have been processed yet.
This patch separates the two. First, we update liveout for all blocks.
At iteration N of the fixed-point algorithm, this uses livein values
from iteration N-1. Secondly, we update livein for all blocks. At
step N, this uses the liveout information we just computed (in step N).
This ensures each computation has a consistent picture of the data,
rather than seeing an random mix of data from steps N-1 and N depending
on the order of the blocks in the CFG data structure.
