rustc_mir_transform: Make DestinationPropagation stable for queries

Browse source 
By using FxIndexMap instead of FxHashMap, so that the order of visiting
of locals is deterministic.

We also need to bless
copy_propagation_arg.foo.DestinationPropagation.panic*.diff. Do not
review the diff of the diff. Instead look at the diff file before and
after this commit. Both before and after this commit, 3 statements are
replaced with nop. It's just that due to change in ordering, different
statements are replaced. But the net result is the same.
