mutated by recursive simplification. This also enhances ReplaceAndSimplifyAllUses to actually do a real RAUW at the end of it, which updates any value handles pointing to "From" to start pointing to "To". This seems useful for debug info and random other VH users. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108415 91177308-0d34-0410-b5e6-96231b3b80d8
