A Builder is now just a Program and a Context.
Details of this CL:
- Builder.imp field removed.
- Builder.globals split up into Package.values and Prog.Builtins.
- Builder.packages moved to Prog.packages.
- Builder.PackageFor moved to Program.Package(types.Object)
- Program.Lookup() func replaces Builder.globals map.
- also: keep Package.info field around until end of BuildPackage.
Planned follow-ups to eliminate Builder from API:
- split NewBuilder up into NewProgram and Program.CreatePackages(...)
- move Builder.BuildAllPackages -> Program.BuildAll(Context)
- move Builder.BuildPackage -> Package.Build(Context)

PLEASE NOTE: the APIs for both "importer" and "ssa" packages
will continue to evolve and both need some polishing; the key
thing is that this CL splits them.
The go.types/importer package contains contains the Importer,
which takes care of the mechanics of loading a set of packages
and type-checking them. It exposes for each package a
PackageInfo containing:
- the package's ASTs (i.e. the input to the typechecker)
- the types.Package object
- the memoization of the typechecker callbacks for identifier
resolution, constant folding and expression type inference.
Method-set computation (and hence bridge-method creation) is
now moved to after creation of all packages: since they are no
longer created in topological order, we can't guarantee the
needed delegate methods exist yet.
ssa.Package no longer has public TypeOf, ObjectOf, ValueOf methods.
The private counterparts are valid only during the build phase.
Also:
- added to go/types an informative error (not crash) for an
importer() returning nil without error.
- removed Package.Name(), barely needed.
- changed Package.String() slightly.
- flag what looks like a bug in makeBridgeMethod. Will follow up.

Implement Pos() method for
Values: Parameter, Capture, Phi. (Not Literal, Builtin.)
Instructions: UnOp, BinOp, Store.
'address' (an lvalue) now needs position of '*' in "*addr".
Also:
- Un-export fields Pos_ Type_ Name_ Block_ from various values/instructions.
Define NewFunction() as a temporary measure.
Will try to eliminate calls from clients...
- Remove Implements{Value,Member,Interface} marker methods.
I've decided I don't like them.
- Func.addParamObj helper.
- Various comment fixes.

PathEnclosingInterval: maps a source position to an ast.Node.
EnclosingFunction: finds ssa.Function enclosing an ast.Node.
HasEnclosingFunction: cheaper impl of EnclosingFunction()!=nil
NodeDescription: user friendly node type descriptions.
+ tests.
Also: make ssa.Package.TypeInfo field a pointer.

Extracted Builder.findMethod function to handle
methodset/receiver logic common to
function calls (Builder.setCall) and
bound method closure creation (Builder.selector).
Capture: added explicit Name, Type fields to Capture instead
of relying on Outer field, which is now un-exported since its
only purpose is to let Builder.expr(case *ast.FuncLit) know
which values to put in the closure; it is nilled immediately
after.
Simplified Function.lookup() logic: there's no need to walk
the Outer chain each time to set Alloc.Heap=true, as it's
already set during creation of the outermost
Capture{outer:*Alloc}.
Added interp/testdata/boundmeth.go test.
Cosmetic changes:
- add support for bound method thunks to Function.FullName().
- Simplified {Literal,Global,Builtin,Function}.String()
- doc: Captures are no longer necessarily addresses.
- added yet another missing pair of "()" (go/types accessors).
- print "Synthetic" not "Declared at -" for synthetic functions.
- use '$' not center-dot in synthetic identifiers (easier to type).
