Alyssa Rosenzweig ff660dd637 agx: Track write registers more accurately
We may not write a full 32-bit vec4, don't be so pessimistic.

Emma Anholt 536c8ee96d nir/lower_tex: Make the adding a 0 LOD to nir_op_tex in the VS optional.
This controls the whole lowering of "make tex ops with implicit
derivatives on non-implicit-derivative stages be tex ops with an explicit
lod of 0 instead", but it's really hard to describe that in a git commit
summary.

All existing callers get it added except:
- nir_to_tgsi which didn't want it.
- nouveau, which didn't want it (fixes regressions in shadowcube and
  shadow2darray with NIR, since the shading languages don't expose txl of
  those sampler types and thus it's not supported in HW)
- optional lowering passes in mesa/st (lower_rect, YUV lowering, etc)

Alyssa Rosenzweig b4108e1d01 agx: Lower UBO loads to use per-element indexing
This lets us support indirect access to UBOs easily. The existing
constant special case disappears too, since the peephole optimizer can
inline the constant later. (note: this is too conservative since we can
go up to 16-bit immediates...)

Unfortunately, nir_opt_algebraic can't seem to optimize expressions like
"((a << 3) + 4) >> 2" to "(a << 1) + 1" which would be necessary for
reasonable perf out of this...

Alyssa Rosenzweig 9645fa9107 agx: Handle discard intrinsics
Lower to `sample_mask = 0`. Actually that implements a demote... doing
discard correctly probably requires rewriting the shader control flow to
insert a return where necessary...

Also, possibly we should be lowering this in NIR to play nice with
gl_SampleMask writes but that's a problem for when we understand the
hardware better.
