s.output.Data() was being retrieved before the synchronization
point, which meant that it could be retrieved before the
goroutine wrote it. Using gccgo this caused random errors.

and switch generation.

Natural, Integer, and Rational numbers
- added Value() methods to access small Natural and Integers
as uint64 or int64 respectively, and to get the components
of Rational numbers
- fixed a bug with Integer creation
- removed some _'s from names
- added more comments in places
- added test cases

* 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.

* 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.
