Alan Donovan b419465131 go.tools/go/ssa: print types package-relative in all instructions.
It was missing from the four conversions and the Make* instructions.

(Experiments with pure bytes.Buffer-based printing were not faster; various TODOs removed.)

Peter Collingbourne 4a6efa0a34 go.tools/go/ssa: add a flag for selecting bare init functions
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.

Alan Donovan 2414677bb9 go.tools/go/loader: add Config.ParserMode configuration parameter.
Existing tools use the default value of zero; their behaviour is unchanged.
(*Config).ParseFile is used only from tests.

Alan Donovan 675033b4f3 go.tools/go/ssa: fix nondeterministic computation of necessary method sets.
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.

% go test -v code.google.com/p/go.tools/go/ssa
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

Alan Donovan 1f29e74bfa go.tools/go/types: remove Type.MethodSet() method.
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)

Alan Donovan 0dcaae1610 go.tools/go/loader: permit Create* methods to specify the ad-hoc package's path
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.

Alan Donovan 3fc0fc1310 go.tools: rename packages.
Was:		Now:
ssa		go/ssa
importer	go/loader
pointer		go/pointer

Next CL: call -> go/callgraph (requires more care)
