5e2185cfbe feat(library/unifier): postpone as much as possible universe constraints of the form ?m1 =?= max(l1, l2) and ?m1 =?= imax(l1, l2) where ?m1 occurs in the right hand side. When there is nothing else to be done, try to solve them by reducing to ?m1 = l1 and ?m1 = l2.

faee08591f fix(*): make sure elaborator and type_checker use the same "rules" for treating opaque definitions
This is a big change because we have to store in constraints whether we can use the "relaxed" rules or not.
The "relaxed" case says that when type checking the value of an opaque definition we can treat other opaque definitions in the same module as transparent.

The new test ../../tests/lean/run/tactic27.lean demonstrates why we need this feature. The tactic 'apply @refl' is actually 'apply @refl.{?l}'. It is used inside of a repeat tactical. Each iteration of the 'repeat' may need to use a different value for ?l. Before this commit, there was not way to say we want a fresh ?l each iteration.
