Banish global state from ScalarEvolution! SCEV uniquing is now done by tables attached to the ScalarEvolution pass. This also throws out the SCEV reference counting scheme, as the the SCEVs now have a lifetime controlled by the ScalarEvolution pass. Note that SCEVHandle is now a no-op, and will be remove in a future commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@73892 91177308-0d34-0410-b5e6-96231b3b80d8
