// testEncodeDecode tests fact encoding and decoding and simulates how package facts
// are passed during analysis. It operates on a group of Go file contents. Then
// for each <package, []lookup> in tests it does the following:
//  1. loads and type checks the package,
//  2. calls (*facts.Decoder).Decode to load the facts exported by its imports,
//  3. exports a myFact Fact for all of package level objects,
//  4. For each lookup for the current package:
//     4.a) lookup the types.Object for a Go source expression in the current package
//     (or confirms one is not expected want=="no object"),
//     4.b) finds a Fact for the object (or confirms one is not expected want=="no fact"),
//     4.c) compares the content of the Fact to want.
//  5. encodes the Facts of the package.
//
// Note: tests are not independent test cases; order matters (as does a package being
// skipped). It changes what Facts can be imported.
//
// Failures are reported on t.
