gallivm: checkpoint: nearest mipmap filtering
The LOD is computed from texcoord partial derivatives and used to
select a mipmap level. Still some bugs in texel fetching. Lots of
rough edges and unfinished parts but the basics are in place.
Lots of changes to the lp_bld_arit.c code to support non-vector/scalar
datatypes.
