  Log Message:
  -----------
  Move delinearization logic out of SCEV [NFC]

None of this logic has anything to do with SCEV's internals, it just uses the existing public APIs.  As a result, we can move the code from ScalarEvolution.cpp/hpp to Delinearization.cpp/hpp with only minor changes.

This was discussed in advance on today's loop opt call.  It turned out to be easy as hoped.
