[PATCH]Unload EH frames in ~MCJIT

[Yaron Keren]

Module loaded with MCJIT register its EH frames with __register_frame to
the runtime library. After MCJIT destructs and the module unloaded,  the
runtime stays with invalid frames of the module, leading to faulty EH
behaviour next time.

This patch calls __deregister_frame upon MCJIT destruction to keep proper
runtime library EH state.
