Meta's GenerateMipmap implementation binds the same image for both sampling and rendering - but it samples from one miplevel while rendering the next. This is a false self-dependency, and there's no need to disable auxiliary buffers in this case. In fact, we really want to leave it enabled so the new miplevels gain color compression. Thankfully, the texture object's _MaxLevel is always one shy of the miplevel being rendered. So we can simply check if irb->mt_level is overlaps with the texture's defined levels. If not, there's no self- dependency and we can leave the auxiliary buffers enabled. Fixes a performance regression in GFXBench4 Car Chase, which apparently calls glGenerateMipmap() on every frame.
