Summary: Add CIF layers to "94" lines, or reorder "types" in tech file

There are two solutions.  First, CIF "94" labels can have a final field
giving the CIF layer to which the label is attached.  You can use the
CIF layername for diffusion (e.g., CDIF) to force the labels to be
attached to {n,p}diffusion by Magic:

    94 Cr:A$ -22 80 CDIF;

Second, the order in which layers are picked for labels whose layers
AREN'T specified in the CIF file is the opposite from the order in which
those layers are defined in the technology file.  If you want {n,p}diff
to be preferable to pwell when both cover a label, define the diffusion
layers LATER in the "types" section of the technology file than pwell.
