The test would nuke the entire contents of os.TempDir on completion.
This change corrects the code to use ioutil.TempDir.

- 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.

parse build tags (not that we make that easy) to automatically skip them.

I cannot create an issue on the tracker for some reason, so here it is:
go vet contains this snippet:
if types.IsAssignableTo(typ, errorType) || types.IsAssignableTo(typ, stringerType) {
It's getting the wrong answer: It claims
interface {
f()
}
or even
interface {
f() float64
}
matches the Error and Stringer interfaces. Both of them. This causes a test failure:
$ go test code.google.com/p/go.tools/cmd/vet
BUG: errchk: testdata/print.go:124: missing expected error: '"for printf verb %s of wrong type"'
$
This worked until very recently.

The old code only got it right for Stringers (etc.) and a few other simple cases.
But the rule used by fmt.Printf for non-Stringers is that pointers to structs
print as pointers, the rest must satisfy the format verb element-wise.
Thus for example
struct {a int, b []byte}
prints with %d and %q (sic) but not %g.

This is useful for situations where one only cares about
exports, for instance (as in the goapi checker).

Remove its 'name' field and treat it just like any other
ssa.Register: it gets a temp name like "t1".
Instead, give it a comment field holding its purpose, e.g, "x"
for a source-level vare, or "new", "slicelit", "complit" or
"varargs".
This improves usability of tools whose UI needs to refer to a
particular allocation site.

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

- 10 classes of errors not checked at the moment

The required changes were surprisingly minimal (I was hoping for a net
code deletion) because ssa is essentially doing its own type inference
for the three value,ok operators---and it continues to have to do so.
To see why, consider:
var i interface{}; var ok bool
i, ok := (map[string]string)(nil)[""]
Before, go/types inferred interface{} for the RHS of the assignment,
and now it infers (interface{}, bool), yet neither of these is what
ssa needs: it needs to know that the map values were strings so
that it can emit a lookup of the right type followed by a conversion
from string to interface{}.

CanonicalPos was inadequate since many pairs of instruction share the same pos (e.g. Allocs and Phis). Instead, we generalize the DebugRef instruction to associate not just Idents but Exprs with ssa.Values.
We no longer store any DebugRefs for constant expressions, to save space. (The type and value of such expressions can be obtained by other means, at a cost in complexity.)
Function.ValueForExpr queries the DebugRef info to return the ssa.Value of a given Expr.
Added tests.
Also:
- the DebugInfo flag is now per package, not global.
It must be set between Create and Build phases if desired.
- {Value,Instruction}.Pos() documentation updated: we still maintain
this information in the instruction stream even in non-debug mode,
but we make fewer claims about its invariants.
- Go and Defer instructions can now use their respective go/defer
token positions (not the call's lparen), so they do.
- SelectState:
Posn token.Pos indicates the <- position
DebugNode ast.Expr is the send stmt or receive expr.
- In building SelectStmt, we introduce extra temporaries in debug
mode to hold the result of the receive in 'case <-ch' even though
this value isn't ordinarily needed.
- Use *SelectState (indirectly) since the struct is getting bigger.
- Document some missing instructions in doc.go.

stdlib_test runs the builder (in sanity-checking mode) over
the Go standard library. It also prints some stats about
the time and memory usage.
Also:
- importer.LoadPackage too (not just doImport) must consult
the cache to avoid creating duplicate Package instances for
the same import path when called serially from a test.
- importer: skip empty directories without an error.
- importer: print all errors, not just the first.
- visit.go: added AllFunctions utility for enumerating all
Functions in a Program.
- ssa.MethodSet is not safe to expose from the package since
it must be accessed under an (inaccessible) lock. (!!!)
This CL makes it unexported and restricts its use to the
single function Program.LookupMethod().
- Program.MethodSet() has gone.
Clients should instead iterate over the types.MethodSet
and call LookupMethod.
- Package.DumpTo(): improved efficiency of methodset printing
(by not creating wrappers) and accuracy (by showing * on
receiver type only when necessary).
- Program.CreatePackage: documented precondition and added
assertion.
