Special case for (fake) package builtin: don't associate
any constant, variable, or factory function with a type.

The "static bool" parameter to Implements was confusing; typically we think about interface implementation and type assertion as separate but related concepts, but here they were merged.

This is intended to replace the awk-based misc/benchcmp.
It mostly matches the existing misc/benchcmp.
Notable changes:
* Written in Go.
* Minor whitespace changes in the output; the tabular nature of the
output is preserved, as is most number formatting and verbiage.
* Comparisons within each section are sorted from highest change to lowest.
* Proper handling of multiple benchmarks with the same name (issue 7016).
* Does not omit benchmark comparisons for which the new value is zero.
* Adds -changed flag to only show benchmarks whose value have changed.
Useful for memory-oriented, large-scale benchmark comparisons.
* Has tests.
* Formats small ns measurements with extra precision.
Updates golang/go#7016.

- Centralize "visited" check in check.objDecl.
- Assert that object-specific declX functions
are only called with objects that have no
type associated with them, yet.
- Added test case.
Thanks to Richard Musiol (neelance@gmail.com) for
finding the bug and providing an easy test case.
For a discussion of the bug see the issue.

- consistently set underlying types of incoming named types in typInternal
- use underlying() helper function to resolve forward chains

This is (a) more efficient and (b) avoids the need for
constant error handling, since buffer writes can't fail.
Also:
- added WriteFunction and WritePackage functions,
similar to types.WriteFoo.
- *Function and *Package now implement io.WriterTo.

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 ...
