To compute the actual liveout/livein data flow values, we start with

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).

Doing it pre-filter would actually have some performance advantage for UNORM
formats (because the comparisons should be done in texture format, we'd only
need to convert the shadow ref coord to texture format once, but in turn would
save converting the per-sample texture values to floats) but this gets a bit
messy as this has implications for border color handling as well (which needs
to be done prior to depth comparisons, hence would also need to convert border
color to texture format too or use some other tricks like doing separate border
color / shadow ref comparison and simply using that result directly when doing
border replacement).
Should make no difference for nearest filtering, and performance for linear
filtering should be mostly the same too (essentially have one more comparison
instruction per sample, and replace the sub/mul/add lerp with a sub/and/and/add
special "lerp" which all in all shouldn't be much of a difference).
