- cleaned up surrounding code
- adjusted error message positions for too few/many argument errors
- added more conversion tests
- added all tests under test/ken to std tests

- support Info.Scopes mapping that maps ast.Nodes
to the respective *Scope
- remove old node link from *Scope
- added corresponding API test
Also: re-enable debug mode (the faster version was
only important for the go api tool, which has its
own version now).

Provide fewer guarantees regarding the collected result
type information in types.Info if there are type errors.
Specifically, don't record nil objects in the Objects map
in case of a declaration error; instead, simply omit them.

If a method cannot type check, we end up with the interface variable
m to hold <*Func, nil>. Don't put that in the map because it defeats
the usual != nil check.

They use stuff in syscall that doesn't exist on Windows, and this test does not
parse build tags (not that we make that easy) to automatically skip them.

exports, for instance (as in the goapi checker).

e.g.
type T int
func (T) f() {}
var t T
_ = t.f // method value: should have signature "func()", no receiver

- ssa: add sanity check that helped diagnose this.

Fixed several bugs:
- lhs blank identifier may be parenthesized: (_) = 0 is ok
- constant shift counts in non-constant shifts must be >= 0
- init functions must have a body
Classified currently failing tests:
- 10 classes of errors not checked at the moment

Also:
- Implement Program.FuncValue for interface methods (+ test).
- go/types.Object.String(): don't package-qualify names unless
they are package level objects---otherwise you see "main.x" for
locals, struct fields, etc.
- go/types.Func.String(): don't assume Type() is *Signature;
it could be *Builtin.

buildDecl was visiting all decls in source order, but the spec
calls for visiting all vars and init() funcs in order, then
all remaining functions. These two passes are now called
buildInit(), buildFuncDecl().
+ Test.
Also:
- Added workaround to gcimporter for Func with pkg==nil.
- Prog.concreteMethods has been merged into Pkg.values.
- Prog.concreteMethod() renamed declaredFunc().
- s/mfunc/obj/ (name cleanup from recent gri CL)

A Method corresponds to a MethodVal Selection;
so the explicit Method object is not needed anymore.
- moved Selection code into separate file

Should make it easier for clients to deal with
selector expressions.
Removed Field type: The respective information
is now reported in Info.Selections.
R=adonovan

We now use LookupFieldOrMethod for all SelectorExprs, and
simplify the logic to discriminate the various cases.
We inline static calls to promoted/indirected functions,
dramatically reducing the number of functions created.
More tests are needed, but I'd like to submit this as-is.
In this CL, we:
- rely less on Id strings. Internally we now use
*types.Method (and its components) almost everywhere.
- stop thinking of types.Methods as objects. They don't
have stable identities. (Hopefully they will become
plain-old structs soon.)
- eliminate receiver indirection wrappers:
indirection and promotion are handled together by makeWrapper.
- Handle the interactions of promotion, indirection and
abstract methods much more cleanly.
- support receiver-bound interface method closures.
- break up builder.selectField so we can re-use parts
(emitFieldSelection).
- add importer.PackageInfo.classifySelector utility.
- delete interfaceMethodIndex()
- delete namedTypeMethodIndex()
- delete isSuperInterface() (replaced by types.IsAssignable)
- call memberFromObject on each declared concrete method's
*types.Func, not on every Method frem each method set, in the
CREATE phase for packages loaded by gcimporter.
go/types:
- document Func, Signature.Recv() better.
- use fmt in {Package,Label}.String
- reimplement Func.String to be prettier and to include method
receivers.
API changes:
- Function.method now holds the types.Method (soon to be
not-an-object) for synthetic wrappers.
- CallCommon.Method now contains an abstract (interface)
method object; was an abstract method index.
- CallCommon.MethodId() gone.
- Program.LookupMethod now takes a *Method not an Id string.

Now, in a "switch y := x.(type)", there is no object for the
outer y, only implicit objects, one per case (including
default).

- implemented objset for tracking duplicates of fields and methods
which permitted a simpler and faster scope implementation in turn
- related cleanups and internal renames
- fixed a couple of identifier reporting bugs
Speed of type-checking itself increased by almost 10%
(from ~71Kloc/s to ~78Kloc/s on one machine, measured
via go test -run=Self).

- more consistent naming of some internal data types and methods
- better factoring of some error reporting code
- cleanup around association of methods with receiver base types
- more tests
R=adonovan
CC=golang-dev
https://golang.org/cl/11726043
- treat receivers like ordinary parameters when checking signatures;
concentrate all respective checks in one place
- continue to type-check methods even if receiver base type does not
satisfy receiver type criteria (comes for free)
- don't ignore blank _ methods anymore
- various related cleanups
As a consequence, the resolving needs one less internal phase.

Temporarily remove Field objects in favor of Vars for struct fields.
In forthcoming CL, Fields will play the symmetric role to Methods, and
serve as lookup results including index information.
