aco: disallow SMEM offsets that are not multiples of 4

These can't be encoded on GFX6/7, and combining these additions causes
CTS failures on GFX10.3.

I think the low 2 MSBs are ignored before the addition, not after, so
load(a + 3, 0) becomes load(a, 3), which is the same as load(a, 0).

No fossil-db changes.
