  Cleanup dyn_hash_{set,map} (#861)

* Require std::unordered_{map,set} for dyn_hash_{map,set}
    This also converts the dyn_hash_* macros to alias templates for better
    type safety and error messages.
* Remove custom hashers for enums
* Use typed enums for IA32Regs, entryID, and prefixEntryID
    This ensures that the std::hash implementation that uses
    std::underlying_type will reflect the old custom hashers.
