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.

walkstate -> walkstmt
walktype -> walkexpr; stmts moved to walkstmt
walktype and friends have a final Node **init
argument that can have side effects appended,
making it more explicit when they do and do not happen.
this replaces the old global addtop and addtotop.
delete switch map and interface conversion cases
(dropped from the language months ago).

(in the same package).
allow forward method declaration to be satisfied
by implementation in another file (in the same package).
all methods must be declared in the same file
as the receiver type.

* 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)

*** Reason for rollback ***
too many files included
*** Original change description ***
simplifying grammar: delete LBASETYPE and LACONST

with method m, s.m() is ok and m now shows up
in s's method set for interface runtime.
see http://cl/28419-p2 for new test interface10.go.

* byteastring is no longer used
* do not generate ODCL, OAS for globals
(wasn't generating any code but might
save one or two init functions)
* do not call self from Init function

was copying a bit too much about t into n,
like whether the signature was queued to be printed.
(bug reported by anton)
was also editing t, meaning you could do
type T int;
func (p int) Meth() { }
both fixed.

this avoids problems people have run into with
multiple closures in the same package.
when preparing filename, only cut off .go, not .anything.
this fixes a bug tgs ran into with foo.pb.go and foo.go
in the same package.
also turn bad identifier chars from filename into
underscores: a-b.pb.go => a_b_pb
