feat(library): instances are not reducible by default anymore
...
Motivation: see "Other goodies" section at
https://github.com/leanprover/lean/wiki/Refactoring-structures
We had to add a new transparency mode: Instances at type_context.
In this mode, instances and reducible definitions are considered
transparent.
The new mode is used in the defeq_canonizer, code generator,
and sizeof lemma generation at inductive_compiler.
We also use the new mode in the unfold tactics.

feat(library/tactic): add options trace.rewrite and trace.kabstract for debugging rewrite tactic
...
See #1480
@semorrison We can now use the following commands to trace the rewrite
tactic
```lean
set_option trace.rewrite true
set_option trace.kabstract true
```
When these options are used, Lean will pretty print the subterm selected
by the rewrite tactic. That is, the subterm that will be rewritten.
This option may help you diagnose what is going on.

See issue #692 .
The implementation still has some rough spots.
It is not clear what the right semantic is.
Moreover, the folds in e_closure could not be eliminated automatically.
