c626e2e3c6 refactor(library/blast): divide hypotheses in: assumption, active and todo 
The sets active and todo are disjoint.

A metavariable declaration can only depend on assumptions.

cb2f93ee6a fix(kernel/expr,kernel/level): performance problem 
The method unordered_set::clear takes time O(n) where n is the number of
buckets in the hashtable used to implement the set.
Moreover, it does not reduce the number of buckets to 0.
That is, it keeps `n` empty buckets.

This creates performance problems if the number of buckets gets really
huge at one point.
The tst6 at tests/kernel/expr.cpp demonstrates the problem

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)
