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.

* 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.

do not bother warning about marks left
on stack after syntax errors.
leave OCONV nodes in tree to avoid type errors
arising from multiple walks.

* 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)

structtype{a:1, a:2}
maptypetype{"xx":1, "xx":2}
arraytypetype{5:1, 5:2}
2. bug in registerization concerning
alias of a struct and one of its elements
3. code optimization of struct.field
(which exposed bug in 2)

TEXT tramp

ADDQ $40, AX
MOVQ AX, 8(SP)
JMP oldfunc
is now
TEXT tramp
ADDQ $40, 8(SP)
JMP oldfunc
and if s/40/0/, then it simplifies to
TEXT tramp
JMP oldfunc
(the tramp is still needed to satisfy
symbol references from other object files)

so that 6l can discard strings used by dead code.
also, for short strings, generate DUPOK global
symbols so that references to, say, "%s: %s" in
multiple files result in only a single symbol.
