This is the initial implementation of IPSCCP, as requested by Brian.
This implements SCCP/ipsccp-basic.ll, rips apart Olden/mst (as described in PR415), and does other nice things. There is still more to come with this, but it's a start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18752 91177308-0d34-0410-b5e6-96231b3b80d8
