- First step towards unified use of scopes. Will enable
further simplifications.
- Removed various ForEach iterators in favor of the existing
accessor methods, for a thinner API.
- Renamed outer/Outer to parent/Parent for scopes.
- Removed check.lookup in favor of Scope.LookupParent.

Also:
- more cleanup of new identifier resolution code
- removed residue Object.Pos() code
- two separate, equally formatted error messages for redeclaration
errors for easier tool support
- initial support for labels
- enabled several disabled tests
Thic CL will break go.tools/ssa/interp, but the pending
CL 9863045 fixes that.
Fixesgolang/go#5504.

By setting resolve = true in check.go, the type checker
will do all identifier resolution during type checking
time and ignore (and not depend on) parser objects. This
permits the type checker to run easily on ASTs that are
not generated with invariants guaranteed by the parser.
There is a lot of new code; much of it slightly modified
copies of old code. There is also a lot of duplication.
After removing the dead code resulting from resolve = true
permanently (and removing the flag as well), it will be
easier to perform a thorough cleanup. As is, there are
too many intertwined code paths.
For now resolve = false. To be enabled in a successor CL.

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.
