	Also, my apologies for spoiling the autocomplete on SimplifyInstructions.cpp. I couldn't think of a better filename. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137229 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-10	Cleanup. Make ScalarEvolution an explicit argument of the	Andrew Trick
	SimplifyIndVar utility since it is required. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137202 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-10	SimplifyIndVar: make foldIVUser iterative to fold a chain of operands.	Andrew Trick

2011-08-10	Added a SimplifyIndVar utility to simplify induction variable users	Andrew Trick
	based on ScalarEvolution without changing the induction variable phis. This utility is the main tool of IndVarSimplifyPass, but the pass also restructures induction variables in strange ways that are sensitive to pass ordering. This provides a way for other loop passes to simplify new uses of induction variables created during transformation. The utility may be used by any pass that preserves ScalarEvolution. Soon LoopUnroll will use it. The net effect in this checkin is to cleanup the IndVarSimplify pass by factoring out the SimplifyIndVar algorithm into a standalone utility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137197 91177308-0d34-0410-b5e6-96231b3b80d8
