Supporting user-defined TestMain functions requires that we generate a
"testmain" package for each testable package, rather than a single one
for the entire program. This entails these API changes:
1. (*ssa.Program).{CreateTestMainPackage,FindTests} both now
accept only a single package. Existing clients that pass them
multiple packages must call them from a loop.
2. (*ssa.Program).FindTests returns an additional result, the the
optional TestMain *ssa.Function. Existing clients may discard it.
Also:
- Test the new logic using the SSA interpreter
- add ssautil.MainPackages helper
- callgraph: allow multiple main packages, and analyze them all
- ssadump -run: allow multiple main/test packages, and run each in a new interpreter
- minor simplifications to some callers (e.g. guru)

This fixes some print calls with wrong format directives. Additionally,
struct initialisers were changed to use keyed fields, purely to reduce
the amount of noise generated by go vet.

A few files have been forked and tagged "go1.5,!go1.6" to work around
minor API changes between the two types packages:
- constant.Value.String() in oracle/describe.go and its tests;
- constant.ToInt must now be called before constant.Int64Val.
- types.Config{Importer: importer.Default()} in a number of places
- go/types/typeutil/import_test.go uses lowercase names to avoid 'import "C"'.
Files in go/types/typesutil, missing from my previous CL, have been
tagged !go1.5; these files will be deleted in February.
All affected packages were tested using 1.4.1, 1.5, and ~1.6 (tip).

This change will ensure that the tree continues to work with go1.4.1.
All files continue to depend on golang.org/x/tools/go/types, but in a
follow-up change, I will switch the primary files to depend on the
standard go/types package. Another (smaller) set of files will be
forked and tagged, this time !1.6, due to API differences between the
two packages.
All tests pass using 1.4.1, 1.5, and ~1.6 (tip).

The optional Qualifier function determines what prefix to attach to
package-level names, enabling clients to qualify packages in different
ways, for example, using only the package name instead of its complete
path, or using the locally appropriate name for package given a set of
(possibly renaming) imports.
Prior to this change, clients wanting this behavior had to copy
hundreds of lines of complex printing logic.
Fun fact: (*types.Package).Path and (*types.Package).Name are valid
Qualifier functions.
We provide the RelativeTo helper function to create Qualifiers so that
the old behavior remains a one-liner.

The loader package now loads, parses, and type-checks a whole program
from source, and that is all.
Also:
- simplified loader logic
- ssa.Create is gone; use ssautil.CreateProgram.
- ssautil.LoadPackage renamed to BuildPackage.
It is now independent of go/types' Import hook and the Packages map.
- ssadump: -importbin flag removed.
The value of this flag was that it caused the tool to print IR
for only a single package; this is now the normal behaviour.

This is a breaking API change, obviously. (One or two tests in this

load source.)

To avoid breaking URLs, we redirect /src/pkg/* to /src/*.
The URL /pkg is now the "directory" /src, which triggers the
"Packages" index.
All other references to "src/pkg" are now gone,
except a number in the namespace documentation which are
probably still illustrative.

Before, Load() would just fail. Now, it gathers all frontend
errors (not just the first go/types error) in PackageInfo.Errors.
There are still cases where Load() can fail hard, e.g. errors in x_test.go
files. That case is trickier to fix and remains a TODO item.

Pointer analysis (currently) takes several minutes.
