would have gotten several.

re-ordering of optimizations and the fact that the NIR deref lowering
code is emitting slightly different instructions.  Nothing was hurt by
more than three instructions and most things weren't helped by more than
four.  The primary exception to this is one Car Chase shader:

    shaders/non-free/gfxbench4/carchase/341.shader_test CS SIMD32: 1144 -> 821 (-28.23%)

Those showed up in the results as hurt instructions but were manually
removed to get the results above.

The lost/gained was a dozen Car Chase shaders that went from SIMD8 to
SIMD16 thanks to improved register pressure:

    shaders/non-free/gfxbench4/carchase/366.shader_test CS

Given how much it appeared to be improved, I ran Car Chase on my laptop.
Unfortunately, I wasn't able to see any measurable improvement.  It
might be helped by 1-2% but it's in the noise.  It does render correctly
as far as I can tell so the improvement is legitimate.

ir3/compiler: Enable lower_io_offsets pass and handle new SSBO intrinsics

These intrinsics have the offset in dwords already computed in the last

the ir3_SHR to divide the byte-offset by 4.

The improvement in shader stats is significant, of up to ~15% in
instruction count in some cases. Tested only on a5xx.

shader-db is unfortunately not very useful here because shaders that use
SSBO require GLSL versions that are not supported by freedreno yet.

For examples, most Khronos CTS tests under 'dEQP-GLES31.functional.ssbo.*'
are helped.

A random case:

dEQP-GLES31.functional.ssbo.layout.2_level_array.packed.row_major_mat3x2

with current master:

; CL prog 14/1: 1252 instructions, 0 half, 48 full
; 8 const, 8 constlen
; 61 (ss), 43 (sy)

; CL prog 14/1: 1053 instructions, 0 half, 45 full
; 7 const, 7 constlen
; 34 (ss), 73 (sy)

The SHR previously emitted for every single SSBO instruction disappears
in most cases, and the dword-offset ends up embedded in the STGB
instruction as immediate in many cases as well.

There are also a few of those tests that are currently failing on register
allocation, that start to pass as a result of reducing the pressure. At least
these, probably more:
