I noticed the inefficiency in NIR-to-TGSI output while trying to debug a
failure handling some arrays in r600. While this makes reading CTS
shaders easier, the effect in the real world is pretty limited. From
softpipe shader-db:
total instructions in shared programs: 2929840 -> 2929836 (<.01%)
instructions in affected programs: 118 -> 114 (-3.39%)

Since we don't have 32-bit ints, these checks for 32-bit unsigned wrapping
don't help and just reduce optimization opportunities (particularly for
DX9 addressing math).
Doesn't affect any current consumers.

This lets nir-to-tgsi fold the constant offset of addressing calculations
into the CONST[] reference, which is important for D3D9-era compatibility:
HW of that age has limited uniform space, and if we do the addressing math
as math in the shader for dynamic indexing, the nir_load_consts end up
taking up uniforms we don't have available.

Doing this for ir3 required adding a struct for limits of how much base to
fold in (which NTT wants as well for its case of shared vars), otherwise
the later work to lower to the 1<<9 word limit would emit more
instructions.
The shader-db results are that sometimes the reduction in NIR instruction
count results in the fewer sampler prefetches due to the shader being
estimated to be shorter (dota2, nexuiz):
total instructions in shared programs: 8996651 -> 8996776 (<.01%)

So far we were checking ARB_shader_image_load_store is supported as
requirement to expose GLES 3.1.
But when this extension functionality was added in GLES 3.1 spec, it
was relaxed, and one of its requirements, the support for formatless
writing, was not included.
So this means that a driver that support all the extension
functionality except formatless writing, could expose GLES 3.1, but it
couldn't expose the extension itself (nor GL 4.2, which requires fully
implementation of the extension).
v2:
- Add the same exposure treatment to ARB_shader_image_size (Ilia).
v3:
- Remove dependency for OES_texture_buffer (Ilia).
- Check image resources for GLES 3.1 (Ilia).
v4:
- Check for MaxImageUniforms in compute shader (Ilia).
- Check for max combined image uniforms/ssbo (Ilia).
v5:
- Remove ARB_shader_image_load_store from check (Ilia).
- ARB_shader_image_store and ARB_shader_image required for
ARB_ES3_1_compatibility (Ilia).

This patch is a rewrite of nir_opt_move.
Differently from the previous version, each instruction is checked
if it can be moved downwards and then inserted before the first user
of the definition. The advantage is that less insert operations are
performed, the original order is kept if two movable instructions have
the same first user, and instructions without user in the same block
are moved towards the end.
v2: Only return true if an instruction really changed the position.
Don't care for discards, this will be handled by another MR.
v3: fix self-referring phis and update according to nir_can_move_instr().
v4: use nir_can_move_instr() and nir_instr_ssa_def()
v5: deduplicate some code
