Steven Wu bb224a3598 [FineGrainedDeps] Fix the non-deterministic .swiftdeps output ...

Fix the non-deterministic .swiftdeps output. In contrary to the comments
in the `FineGrainedDependencies.h`, the non-determinism is not because
of the use of unordered_* data structure there. Those data structures
are not traversed so removing all the unused traversing methods to avoid
the confusion.

The true reason for the non-determinism is all the DenseSet in the
Evaluator dependency tracking, that causes the FineGrainedDependencies
to see arbitrary ordering. Use `SetVector` instead to keep track of the
insertion order to make dependency output to be deterministic.
