Minor fixes in typeclasses, avoiding repeated evar normalizations.
Improve generalization by equalities tactic, now allowing to
generalize an arbitrary application, e.g. in preparation for applying an
elimination principle for a function. This adds a flag to generalize_dep
so that it doesn't abstract the variable if it is defined, just
introducing a let-in.
