Find a more efficient fix for dealing with template universes:
eagerly solve l <= k constraints as k := l when k is a fresh variable coming
from a template type. This has the effect of fixing the variable at the first
instantiation of the parameters of template polymorphic inductive and avoiding
to generate useless <= constraints that need to be minimized afterwards.
