Minor unification changes:
- Primitive setup for firing typeclass resolution on-demand: add a flag to
control resolution of remaining evars (e.g. typeclasses) during
unification.
- Prevent canonical projection resolution when no delta is allowed
during unification (fixes incompatibility found in ssreflect).
- Correctly check types when the head is an evar _or_ a meta in w_unify.
Move [isEvar_or_Meta] to kernel/term.ml, it's used in two places now.
