e52e9ca82e another step toward eliminating forward declarations. 
introduce NodeList* type in compiler to replace OLIST.
this clarifies where lists can and cannot occur.
list append and concatenation are now cheap.
the _r rules are gone from yacc.
rev and unrev are gone.
no more lists of lists.

the representation of assignments is a bit clunkier.
split into OAS (1=1) and OAS2 (2 or more on one side).

delete dead chanrecv3 code.

delay construction of func types.

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.

arising from multiple walks.

e81d97ea84 clean up gmove: 
* conversions all in one place.
	* no separate load, store phases;
	  direct memory addressing when possible
	  (this is the x86 after all!).
	  avoids extra registers, extra MOVQs.
	* fixes int32 -> uint64 bug
	  (was zero-extending)
