d515063588 better handling of mistaken top-level variable
references during the parsing of :=.  the base
problem is that when reading

	a,b,c,d

the parser makes those refer to existing variables,
which might create a few stub top-level ones
for undefined names, but then if a := is the next
token, we need to undo those stubs.

this was causing problems in multifile packages
in which one file used a := variable named rpc
and the other imported a package named rpc.

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.

01fe6a9c58 more build refinements:
* use new Make.$GOARCH files in gobuild.
 * rename 6ar to arch-generic gopack.
 * place objects in $GOROOT/pkg/$GOOS_$GOARCH
   (makes cross-compiling easier, and no one
   ever types these paths by hand anyway).

f95da9a639 yet another attempt at auto-linking
store only the original import path string (+ .a)

let 6l re-resolve the .a at link time.

this lets libraries build against an archive
in the current directory but get used
against an installed archive.

416b27548e use _f007·filename for func literals.
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
