-- Add a pass to reorder functions by name, which can be useful for debugging
-  (e.g. comparisons after optimizations), `--reorder-functions-by-name`.
-- C API: Add BinaryenAddFunctionWithHeapType() which is like BinaryenAddFunction
-  but takes a heap type. The old function is kept for backwards compatibility
-  and as a convenience.
