- factor out argument extraction logic
- cleaned up error handling in builtin.go (no need for goto's anymore)
- lots of additional test cases
- various cleanups, better documentation
Fixesgolang/go#5795.

It would be nice to be able to use this package
as a dependency (or other go utilities in the
ecosystem that depend on this package) in
environments which have not (or cannot) for
whatever reason upgraded to newer versions of
golang.

In general, if a break or continue label is not found, we don't
know if a correspondingly named label was not declared, was declared
but is not visible, or will be declared (and won't be visible).
Complain about "invalid" rather than "not declared" label.
Added more tests.

This CL temporarily removes some preliminary label checks.
They will be implemented completely in a subsequent CL.

This change affects the API: Func objects now always have a *Signature
as type (never a *Builtin). Instead, built-ins now appear as *Builtin
objects. Only the built-in name is exposed, other fields are now private
to go/types.
Several bugs are fixed:
- correctly checking for built-ins permitted in statement context
- expression statements that are calls are not type-checked twice anymore
- go/defer statements report call types and provide good error messages now
This CL will briefly break the build until CL 13848043 is submitted.

it does not reflect actual use/def information

2. indices provided for array or slice composite literals must be integer constants

And: add accessor to get the primary from a secondary Package.
This change documents a surprising fact about the current
go/types resolver implementation, namely that each ast.ImportSpec
import "fmt"
creates a new ("secondary") Package object for fmt with the
same String, Name, Path and Scope as the canonical ("primary")
fmt package, but with a different identity.
This change also adds an accessor Package.Primary() that
returns the primary package associated with a secondary
package object, if any.
IMHO the current design is wrong, and the resolver should not
create secondary packages at all. Even if a package is
imported under a non-default name, as in
import f "fmt"
...
f.Print
we should just regard f as a reference to the existing package
"fmt", not as the defining identifier for a secondary package.
What we would lose by such a change (the connection of the two
f's in 'f.Print' and 'import f "fmt"') seems a small price to
pay.
This CL is thus just a minimal change to permit clients to
make progress under the status quo.

using it in error message).

- Exported ByCmd and FromDir functions for constructing Cmd
- Exported TagCmd

- 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
