This results in significant improvement to type-checking time:
it reduces by 4% the entire running time of ssa/stdlib_test
(GOMAXPROCS=8, n=7).

Since Put() makes a dynamic function call, this CL includes a long-overdue change to supply a *frame (and thus the call
stack and the interpreter) to intrinsics too.
This fixes the tests that were broken by (sound) revision e4a4cb47c141.

CL 49530047 made the (over-)simplifying assumption that the
Path of an ad-hoc (Created) package should default to its
Name, i.e. package declaration.
With this change, the Name is still always computed from the
package declaration (by go/types) but the Path may be
specified by the loader.Config. If "", the value of the Name
is used, which is not globally unique.

Was: Now:
call.Graph callgraph.Graph
call.GraphNode callgraph.Node
call.Edge callgraph.Edge
Though call.Graph was cute, the original naming was a mistake:
'call' is too useful a var name to waste on a package.

The Importer type has been replaced with Config and Program.
Clients populate a Config, directly or more usually via
convenience functions. They then call its Load() method to do
all of the typechecking and transitive-closure computation.
ssa.NewProgram and ssa.CreatePackages have been fused into
ssa.Create, which now cannot fail, since (*Config).Load()
reports all type errors.
Also:
- The addition of an ssa.GlobalDebug builder mode flag
eliminates a loop-over-packages repeated in many clients.
- PackageInfo.Err flag unexported. Clients never see bad infos now.
- cmd/ssadump: now only looks for func "main" in package "main".
- importsOf deleted, was dead code.
STILL TODO:
- ParseFile seems like API creep (though it's convenient)
and CreateFromFiles is dangerous (w.r.t. FileSet identity).
Need to think more...
- the need for clients to rely on elementwise correspondence
of Config.CreatePkgs and Program.Created is a little sad.
- The command-line interface has not changed.
That will happen in a follow-up.
r recommends using a repeated flag: -package p -package q ...

The goal is to allow clients to distinguish function-local objects
from package-local objects and identify the specific function by
examining its scope. For example, a compiler may need to mangle
object names according to the outer function name.

go/types no longer reports a constant value for a slice,
e.g. []byte("foo").
ssa.Const no longer support slice constants, only
bool/string/numeric and nil.
emitConv emits a Convert instruction for string->[]byte
conversions.
Added regression test for bug 6949.

The issue is addressed with the change in conversions.go.
Also:
- added corresponding API test
- made names for untyped ints, bools consistent with others
- use *Basic with names byte/rune instead of uint8/int32 for better output
- minor cleanups

Packages were not being created for all types.Packages,
specifically, indirectly imported packages were missing.
(*Program).CreatePackages now iterates over the type-checker's
package map too.
Also: removed all concurrency from importer. I think it was
incorrect (and hard to fix).
Also: change LoadInitialPackages so that all named packages
are loaded from source. This happens regardless of whether
GCImporter is used to satisfy imports.
Details:
- importer.Config.SourceImports flag determines whether to
load all packages from *.go source.
(Before, this was indicated by Config.Build != nil.)
- importer.Config.Build field effectively defaults to
&go/build.Default. A zero importer.Config is now usable.
- importer.Importer.Config field is now exported.
- LoadPackage renamed to ImportPackage since the resulting
packages may come from GCImporter (and be incomplete).
- doImport and ImportPackage fused.

Also report an error for "cross-interpretation": not supported
due to the interpreter's assumption that host and target
{int,uint,uintptr} are the same. (Too tedious and messy to fix.)
Tested manually:
% cat d.go
package main
const m = ^uintptr(0)
const w = m>>8&1 + m>>16&1 + m>>32&1
func main() { println(m, w) }
% ./ssadump -build=P -run d.go
package main:
const m m = 18446744073709551615:uintptr
const w w = 3:uintptr
18446744073709551615 3
% GOARCH=386 ./ssadump -build=P -run d.go
package main:
const m m = 4294967295:uintptr
const w w = 2:uintptr
Error: Cross-interpretation is not yet supported (target has GOARCH 386, interpreter has amd64).

This can import all of the standard library, and has been tested
by using gotype to type check libgo with gccgo's export data (this
would be nice to automate, but I can't see a good way to do it,
not least because system-specific source files cause errors which
I needed to identify manually).
It includes a builtin export locator. Unfortunately I can't see a
more reliable way to locate the builtin export files than to parse
the output of 'gccgo -###'.

(the old code did the same, but more circuitously)
