Robert Griesemer f50f6c858a go.tools/go/types: nil is not a constant + misc. cleanups
- removed support for nil constants from go/exact
- instead define a singleton Nil Object (the nil _value_)
- in assignments, follow more closely spec wording
  (pending spec CL 14415043)
- removed use of goto in checker.unary
- cleanup around handling of isRepresentable for
  constants, with better error messages
- fix missing checks in checker.convertUntyped
- added isTyped (== !isUntyped) and isInterface predicates
- fixed hasNil predicate: unsafe.Pointer also has nil
- adjusted ssa per adonovan
- implememted types.Implements (wrapper arounfd types.MissingMethod)
- use types.Implements in vet (and fix a bug)

Robert Griesemer cc52b8b7f8 go.tools/go/types: clean up assignment checks (round 1)
Various bug fixes:
- don't allow := to redeclare non-variables
- don't permit a comma-ok expression as a two-value function return

Lots of dead code removed.

Fixes golang/go#5500.

Rob Pike 01f8cd246d go.tools: add go/types, ssa, and cmd/vet
They will be deleted from their current homes once this has landed.
Changes made to import paths to make the code compile, and to find
errchk in the right place in cmd/vet's Makefile.
TODO in a later CL: tidy up vet.
