47caefc7b4 v3d: Force sampling from base level for tg4. 
This is what the GLSL ES 310 spec tells us to do, but apparently the
"gather mode" flag doesn't imply it in the HW.  Fixes
dEQP-GLES31.functional.texture.gather.basic.2d.rgba8.filter_mode.min_nearest_mipmap_linear_mag_linear

29927e7524 v3d: Drop in a bunch of notes about performance improvement opportunities. 
These have all been floating in my head, and while I've thought about
encoding them in issues on gitlab once they're enabled, they also make
sense to just have in the area of the code you'll need to work in.

26f830d9fc v3d: Add an assert that we don't provide an invalid texture return words. 
The docs had an update noting this restriction, so reflect it in the code.

Fixes simulator assertion failures in
dEQP-GLES3.functional.shaders.texture_functions.texture.samplercubeshadow_bias_fragment
