[LLVMdev] Thread-safe cloning

[Reid Kleckner]

You could probably round trip it through bitcode in memory.  I think all of
the IR cloning functionality assumes that only one context is being used.
 Even if the serialization isn't efficient as a clone could be, it should
give you very high confidence that everything Just Works.  :)
