Merged requested to merge icecream95/mesa:neg-lodbias into master
The shader-based lod bias workaround doesn't seem to need any changes for this to work.
pandecode should probably also work without change, but I haven't tested it.
Although lod_bias can be negative, min_lod and max_lod need to be positive, but I still changed them to
int16_t for consistency and to prevent compilers from complaining about casting
