f8d472c9f1 feat(frontends/lean/parse_rewrite_tactic): change the semantics of rewrite[↑f] when f is recursive 
After this commit it behaves like 'unfold f'.
That is, it will unfold f even if it fails to fold recursive
applications. Now, only 'esimp[f]' will not unfold f-applications when
it cannot fold the recursive applications.

This commit also closes #692. It is part of a series of commits that
addresses this issue.

e7c3c887b6 feat(kernel/type_checker): add 'check' procedure that uses 'opaque_hints' 
The hints only affect performance. If a declaration type checks assuming
some constants are opaque, it should also type check without this
assumption. Of course, it may be much slower.

1e6550eda6 feat(kernel/default_converter): take into account the 'theorem' annotations in the converability checker 
The idea is that we should seldon need to unfold theorems.
The convertability checker should use that.
When the convertability checker was implemented, theorems were opaque in
Lean. So, this hint was not needed.

This modification is another workaround for the performance problem with
the migrate command at library/data/real/division.lean.
This solution is better than applying proof irrelevance eagerly because
it also addresses similar problems in the HoTT library which does not
support proof irrelevance.

This commit also enables the conv_opt for all theorems.

11fbee269b fix(frontends/lean/parser): must save state of name_generator in parser snapshot 
To provide typing and auto-completion information, we create a
background process by starting lean with the option --server.
In "server" mode, we create snapshots of the parser state.
The idea is to be able to quickly reprocess a file when the user makes a
modification. This commit fixes a bug in the snapshot operation.
It was not saving in the snapshots the unique name generator used by the parser.
By creating a fresh name generator, we may accidentally
assign the same internal name to two different constants.
This bug triggered the crash described in issue #593.

This commit fixes the test in the comment
https://github.com/leanprover/lean/issues/593#issuecomment-101768484
