In terms of mangling, it reorders your vector operations, which can drastically hurt performance.

Do any production compilers schedule instructions to maximize superscalar performance?

Um, unless I misunderstand your question, virtually all of them do. In particular, GCC, Clang/LLVM and ICC all do instruction scheduling.
