before the expression root. Any existing operators that are changed to use one of them needs to be moved between it and the expression root, and recursively for the operators using that one. When I rewrote RewriteExprTree I accidentally inverted the logic, resulting in the compacting going down from operators to operands rather than up from operands to the operators using them, oops. Fix this, resolving PR12963. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159265 91177308-0d34-0410-b5e6-96231b3b80d8
