This matches what NVIDIA and AMD hardware expose.

Not sure what the true HW limit is here. On NVIDIA, the true HW limit really
is -32/31 though. As an aside, according to vulkan.gpuinfo.org, the Intel
Windows driver also exposes -32/31.
With the updated limits on SKL, everything still passes:
./deqp-vk --deqp-visibility=hidden --deqp-case='*texture_gather*'
Test run totals:
Passed: 762/1524 (50.0%)
Failed: 0/1524 (0.0%)
Not supported: 762/1524 (50.0%)
Warnings: 0/1524 (0.0%)
