c652eeeac6 feat(library/data/expr): add support for regular local constants in blast tactic 
We need them when inferring types and checking whether two expressions
are definitionally equal or not.

Remark: they are temporary objects, and should never be included in the
blast state object.

bb24421232 feat(library/blast): add hash consing for expressions (and universe levels) created in blast 
We had to reimplement the expr API: replace, abstract, instantiate.

Remark: blast expressions do not use metavariables and local constants,
but the new mref and lref expressions.

08169c5ac2 fix(library/unifier): fixes #809 
Daniel is correct when he says the interaction between choice
case-splits, delta case-splits, and coercions can be subtle.

I believe the following condition
https://github.com/leanprover/lean/blob/master/src/frontends/lean/elaborator.cpp#L111
reduces counter-intuitive behavior. Example, the coercion should not
influence the resulting type.
BTW, by removing this condition, many files in the library broke when I
tried to compile from scratch

      make clean-olean
      make

I used the following workaround. Given a delta-delta constraint

           f a =?= f b

If the terms are types, and no case-split will be performed, then
the delta-delta constraint is eagerly solved.
In principle, we don't need the condition that the terms are types.
However, many files break if we remove it. The problem is that many files in the standard
library are abusing the higher-order unification procedure. The
elaboration problems are quite tricky to solve.
I use the extra condition "the terms are types" because usually if they
are, "f" is morally injective, and we don't really want to unfold it.

Note that the following two cases do not work

     check '{1, 2, 3}
     check insert 1 (insert 2 (insert 3 empty))

Well, they work if we the num namespace is open, and they are
interpreted as having type (finset num)
