9399ce8346 feat(library/vm/vm_string): provide native implementation of type string in the VM 
closes #1175

The types `string_imp` and `string.iterator_imp` were supposed to be
marked private, but we cannot do it because we need to provide
`string_imp.mk`, `string_imp.cases_on`, `string.iterator_imp.mk` and
`string.iterator_imp.cases_on` in the VM since we use a different
internal representation. Note that marking them as private does not
work since users can still access `string_imp.cases_on` using
meta-programming.
So, we need better support for private declarations.

Missing feature, char literals do not support non ASCII values.
That is, in the current implementation, we cannot write 'α'.
This will be implemented in the future.

The VM native implementation does not behave correctly for huge
strings (i.e., strings with more than 4G characters).
The problem is that the current implementation relies on
```
size_t force_to_size_t(vm_obj const & o, size_t def)
```
We may also have overflow problems in the string.iterator implementation
code. This is not a big deal right now, since I doubt we will try
to process string with more than 2^32 characters.

@Kha the `core_lib` and tests seem to be working correctly, but
we need more tests.

d4f2bb77b8 feat(frontends/lean): recursive equation preprocessor 
To make the equation compiler more convenient to use, we will add a
couple of preprocessing steps.
This commit adds the first one of them. In this step, we use
type inference to refine pattern variables, and we relax the
restrictions on inaccessible annotations.

We will also add a preprocessing step that implements the "complete
transition" step before we execute the elim_match step.

0c15724e8e fix(library/tactic/simplify): handle universe polymorphic simplification rules 
The issue was that instantiate_mvars(infer(m)) had a metavariable, while
infer(instantiate_mvars(m)) did not.  Changing the call from assign to
is_def_eq also unifies the type, assigning the metavariable inside the
type.
