  Preserve use-list orders in mlir bytecode

This patch implements a mechanism to read/write use-list orders from/to the mlir bytecode format. When producing bytecode, use-list orders are appended to each value of the IR. When reading bytecode, use-lists orders are loaded in memory and used at the end of parsing to sort the existing use-list chains.
