d8f3bcec67 feat(library/init/logic): add 'arbitrary' 
It is identical to default, but it is opaque.
That is, when we use 'arbitrary A', we cannot rely on the particular
value selected.

4781fc8365 fix(library/init/logic): eq.symm should not use eq.subst 
Reason: eq.symm is used by definitional package, and eq.subst is opaque.
Thus, computation will get stuck if it depends on eq.subst.

After this commit, Lean "cuts" the search after the first instance is
computed. To obtain the previous behavior, we must use the new command
