  -----------
  Fix DenseMap iterator asserts when shouldReverseIterate==true

This patch gets the asserts working correctly when LLVM_REVERSE_ITERATION=On by fixing the iterators returned by the DenseMap::find* methods so that they return well-formed iterators that work with reverse iteration, and satisfy the assertions.
