Currently the NIR backends depend on GLSL IR copy propagation to
fix up the interpolateAt* function params after varying packing
changes the shader input to a global. It's possible copy propagation
might not always do what we need it too, and we also shouldn't
depend on optimisations to do this type of thing for us.
I'm not sure if the same is true for TGSI, but the following
commit should re-enable packing for most cases in a safer way,
so we just disable it everywhere.

V2: mark float opts as inexact
If one of the inputs to an mul/add is the result of another
mul/add there is a chance that we can reuse the result of that
mul/add in other calls if we do the multiplication in the right
order.
Also by attempting to move all constants to the top we increase
the chance of constant folding.
For example it is a fairly common pattern for shaders to do something
similar to this:
const float a = 0.5;
in vec4 b;
in float c;
...
b.x = b.x * c;
b.y = b.y * c;
...
b.x = b.x * a + a;
b.y = b.y * a + a;
So by simply detecting that constant a is part of the multiplication
in ffma and switching it with previous fmul that updates b we end up
with:
...
c = a * c;
...
b.x = b.x * c + a;
b.y = b.y * c + a;

Some queries on a4xx and all queries on a5xx can do result accumulation
on CP so we don't need to track per-tile samples. We do still need to
handle pausing/resuming while switching batches (in case the query is
active over multiple draws which are executed out of order).
So introduce new accumulated-query helpers for these sorts of queries,
since it doesn't really fit in cleanly with the original query infra-
structure.

For a5xx (and actually some queries on a4xx) we can accumulate results

opt_register_coalesce() was optimizing sequences such as:
mul(8) acc0:D, attr18.xyyy:D, attr19.xyyy:D
mach(8) vgrf5.xy:D, attr18.xyyy:D, attr19.xyyy:D
mov(8) m4.zw:F, vgrf5.xxxy:F
into:
mul(8) acc0:D, attr18.xyyy:D, attr19.xyyy:D
mach(8) m4.zw:D, attr18.xxxy:D, attr19.xxxy:D
This doesn't work - if we're going to reswizzle MACH, we'd need to
reswizzle the MUL as well. Here, the MUL fills the accumulator's .zw
components with attr18.yy * attr19.yy. But the MACH instruction expects
.z to contain attr18.x * attr19.x. Bogus results ensue.
