2acbc37166 various 6g cleanup:
* give genwrapper and genembedtramp the same signature.
* move duint8, duint16, duint32, duint64, duintptr into gc.
* tidy genwrapper.
* bug involving struct field symbols in signature list.
  (hash-order dependent so hard to trigger)
* new Type print format %#-T like %#T but omits
  names on function arguments.

4793400bd1 new reflect library data structures and code declarations
* use structs instead of interfaces
  * compiler lays out data structures ahead of time,
    so no more parsing of strings.
  * unified reflect data structures with interface
    runtime data structures.
  * richer data structures should enable reflection
    on chans and maps, but not implemented here.
