pan/midgard: Compute liveness per-block
Rather than using a regalloc based on live internals, computed hastily
with repeated invocations of a forward-analysis pass, we switch to
compute liveness information on a per-block basis.
Within a given basic block, we compute liveness backwards with a
linear-time algorithm; for common shaders, this may help RA terminate
quicker.
Across blocks, we use a work list (really a work set) and check if we're
making progress. This isn't terribly efficient, but it gets the job
done. Point is, we get the live_in/live_out for each block.
From there, it's simple to rerun the linear-time update algorithm to
compute the interference graph.
The benefit of this technique is the ability to ignore "gaps" in
liveness across intermediate blocks that are never executed. On simple
shaders like the loops in glmark, this results in a minor reduction in
register pressure. The motivation was a complex shader in Krita that
failed register allocation due to an unfortunate interaction between
texture pipeline registers and control flow. This shader now compiles
successfully.

nir/algebraic: Reassociate add-and-shift to be shift-and-add
A common thing in many shaders:
uniform vs { vec4 bones[...]; };
...
x = some_calculation(bones[i + 0]);
y = some_calculation(bones[i + 1]);
z = some_calculation(bones[i + 2]);
This turns into stuff like
vec1 32 ssa_12 = iadd ssa_11, ssa_0
vec1 32 ssa_13 = ishl ssa_12, ssa_3
vec1 32 ssa_14 = intrinsic load_ssbo (ssa_7, ssa_13) (16, 4, 0)
vec1 32 ssa_15 = iadd ssa_11, ssa_1
vec1 32 ssa_16 = ishl ssa_15, ssa_3
vec1 32 ssa_17 = intrinsic load_ssbo (ssa_7, ssa_16) (16, 4, 0)
vec1 32 ssa_18 = iadd ssa_11, ssa_2
vec1 32 ssa_19 = ishl ssa_18, ssa_3
vec1 32 ssa_20 = intrinsic load_ssbo (ssa_7, ssa_19) (16, 4, 0)
By reassociating the shift and the add, we can reduce this to
vec1 32 ssa_12 = ishl ssa_11, ssa_3
vec1 32 ssa_13 = iadd ssa_12, ssa_0
vec1 32 ssa_14 = intrinsic load_ssbo (ssa_7, ssa_13) (16, 4, 0)
vec1 32 ssa_16 = iadd ssa_12, ssa_1
vec1 32 ssa_17 = intrinsic load_ssbo (ssa_7, ssa_16) (16, 4, 0)
