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.

...since the zero value is more useful by far.
This is a breaking API change, obviously. (One or two tests in this
CL have intentional been left using the zero value, i.e., they now
load source.)

Details:
- rename (*Program).TypesWithMethodSets() to RuntimeTypes()
- delete (*Package).TypesWithMethodSets() method and simplify
- move code to methods.go
- update test to use
1-2% improvement in space and time (though I barely trust this data
because the GC at tip is in such terrible state).

Bare init functions omit calls to dependent init functions and the
use of an init guard. They are useful in cases where the client uses
a different calling convention for init functions, or cases where
it is easier for a client to analyze bare init functions.

Method Signatures (types.Signatures with a non-nil receiver) behave
like ordinary func Signatures in the hash function/equivalence relation
used by typemap.M, which leads to surprising incomplete traversal
over the type graph if an M is used to remember types already
visited.
This change avoids ever putting method Signatures in a typemap.

now repeatedly shows the exact same number of functions and
instructions.
(We should discuss how to avoid this problem more generally.)
Also:
- recur over the params/results of all the methods of
each type when computing necessary method sets.
- there's no longer any need to treat declarations of unexported
methods as a root for traversal. Added test case.
- enable SourceImports flag in stdlib_test, which was dropped
during a recent refactoring (d'oh).
- doc tweaks

Method-set caching is now performed externally using a MethodSetCache (if desired), not by the Types themselves.
This a minor deoptimization due to the extra maps, but avoids a situation in which method-sets are computed and frozen prematurely. (See b/7114)

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.
