Dan Gohman c056454ecf Remove the Expr member from IVUsers. Instead of remembering the expression, ... just ask ScalarEvolution for it on demand. This helps IVUsers be more robust in the case of expressions changing underneath it. This fixes PR6862. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101819 91177308-0d34-0410-b5e6-96231b3b80d8		2010-04-19 21:48:58 +00:00
