Title: removes Type.isConcrete

This method was no longer used anywhere, except for a place where it wasn't
really necessary.

Its implementation is non-trivial, and I have doubts about it, so I propose
to remove it altogether instead of living with some dubious code necessary
for some dubious matter.
