The eta-expansion contains invalid projections, and the eta-rule is
subsumed by proof irrelevance anyhow.

old default values are too small.

fix: use a def-eq aware mapping at toLinearExpr

The new test exposes the problem fixed by this commit.
In the termination proof we have two `sizeOf xs` terms that are not
syntactically identical (only definitional equal) because the
instances are different.
