    gallivm: use the new mip per quad handling in texture fetch path
    
    No longer have to split fetching into quads dynamically if mip levels
    are not the same for all quads (aos sampling still always splits due
    to performance reasons).
    Instead handle multiple mip levels further down, minification etc. takes
    this into account.
