9c9e8c3349 nir: Reorder ffma and fsub combining 
It's relatively common to do something like "a * b - c", which on most
GPUs can be implemented in a single instruction. Before
opt_algebraic_late this will be something like
"fadd(fmul(a, b), fneg(c))", and we want to turn it info
"ffma(a, b, fneg(c))". But because the fsub pattern was first we
instead turned it into "fsub(fmul(a, b), c)". Fix this by reordering
them.

f6ffefba3e nir: Apply nir_opt_offsets to nir_intrinsic_load_uniform as well. 
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):

3b81d2d30d mesa/st: do not expose ARB_shader_image_load_store if not fully implemented 
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).

As this optimizations moves code into the NIF statement,
it re-iterates on the branch legs in case of success.

8a78706643 nir: refactor nir_opt_move 
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

558a600629 nir_to_tgsi: Enable fdot_replicates flag. 
That's how the TGSI math opcodes work.

This lets lower_vec_to_regs coalesce the DP output into the .yzw channels,
giving an impressive shader-db win on softpipe:

total instructions in shared programs: 2929840 -> 2794036 (-4.64%)
instructions in affected programs: 1651438 -> 1515634 (-8.22%)
total temps in shared programs: 372730 -> 332744 (-10.73%)
temps in affected programs: 118151 -> 78165 (-33.84%)

and a minor one on r300:

total instructions in shared programs: 51238 -> 51149 (-0.17%)
instructions in affected programs: 2621 -> 2532 (-3.40%)
total vinst in shared programs: 15655 -> 15618 (-0.24%)
vinst in affected programs: 468 -> 431 (-7.91%)
total temps in shared programs: 9838 -> 9828 (-0.10%)
temps in affected programs: 59 -> 49 (-16.95%)

and a bigger one on i915g:
total instructions in shared programs: 398064 -> 395901 (-0.54%)
instructions in affected programs: 29271 -> 27108 (-7.39%)
total tex_indirect in shared programs: 12261 -> 12233 (-0.23%)
tex_indirect in affected programs: 98 -> 70 (-28.57%)
LOST:   0
GAINED: 5

The r300 change is less impressive because it does some backend copy-prop,
but also because intermediate storage of DPs now takes a vec4 instead of a
scalar.
