94e6fbcbbf perf(library/vm/vm): make sure builtin cases_on recursors are assigned ids first 
This will minimize the size of the m_builtin_cases_vector.
It also indirectly prevents the crash decribed at 144d9096e2.
However, the fix used there is more robust.

144d9096e2 fix(library/vm/vm): serialization/deserialization of builtin cases_on instruction 
We generate internal ids for builtin cases_on recursors.
These ids were being saved in the .olean files.
This was fine before commit 41e8a1712e because we had a separate
mapping for builtin cases_on recursors. Now, all ids are stored in the
same mapping. Thus, minor changes in the set of VM builtin operations
make lean crash when importing .olean files because they will change the
internal id for the builtin cases_on.
The problem can be reproduced in the following way:

0- Go to build/release

1- make clean-olean

2- make
Everything is fine after step 2

3- Comment the following line at tactic_state.cpp

    DECLARE_VM_BUILTIN(name({"tactic", "open_namespaces"}),      tactic_open_namespaces);

4- make

5- Lean will crash when executing the following command

   ../../bin/lean ../../library/init/meta/tactic.lean

I believe this bug is reponsible by the crash that @jroesch reported on Slack.

This commit fixes the problem by storing the name of the builtin
cases_on recursor in the .olean file.

e5c4231248 fix(library/vm/vm): bug at vm_index_manager? 
@gebner, I have been experiencing crashes that are hard to reproduce.
I think one of the problems was that get_vm_name was returning a `name const &`.
I think this may produce a memory access violation in the following
scenario:

1- Thread 1 invokes get_vm_name, and gets a reference R. This is a
   reference to a memory cell in the vector m_idx2name.
2- Thread 2 invokes get_vm_index, and it triggers a vector resize
   operation. After the resize, reference R is invalid.
3- Thread 1 crashes trying to access R.

49e296dee2 fix(library/type_context, library/tactic/induction_tactic): fix for issue #1258 was incorrect 
The fix was incorrect because it could produce an invalid local context.
Actually, the regression tests/lean/run/1258.lean was producing an
assertion violation.
