[PATCH] Address Space Casting

[Michele Scandale]

  Here a new version of the patch that keep addrspacecast instruction: I applied the modification you suggested and reviewed the CastInst::isEliminableCastPair static method in order to be consistent with the new semantic and modified its unit test.

  About the C bindings, please confirm me if the enumeration of the opcodes can be changed or if it must be binary compatible with the previous version.

  Thanks.
