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.

Extracted Builder.findMethod function to handle
methodset/receiver logic common to
function calls (Builder.setCall) and
bound method closure creation (Builder.selector).
Capture: added explicit Name, Type fields to Capture instead
of relying on Outer field, which is now un-exported since its
only purpose is to let Builder.expr(case *ast.FuncLit) know
which values to put in the closure; it is nilled immediately
after.
Simplified Function.lookup() logic: there's no need to walk
the Outer chain each time to set Alloc.Heap=true, as it's
already set during creation of the outermost
Capture{outer:*Alloc}.
Added interp/testdata/boundmeth.go test.
Cosmetic changes:
- add support for bound method thunks to Function.FullName().
- Simplified {Literal,Global,Builtin,Function}.String()
- doc: Captures are no longer necessarily addresses.
- added yet another missing pair of "()" (go/types accessors).
- print "Synthetic" not "Declared at -" for synthetic functions.
- use '$' not center-dot in synthetic identifiers (easier to type).

- remove Makefile
- move test data into a subdirectory
- encapsulate the invocation of errchk into a standard Test using os.exec

Now that it's in the same repository as the go/types package we can delete
the mechanism to build it without type checking.
Add a make rule to install it where the go tool can find it.
Why doesn't "go install" take a -o flag?

Also:
- remove redundant text in doc.go.
- fix (yet more) cases of missing parens in Printf, fallout from
go/types accessors refactoring.
- don't mix spaces and tabs within lines printed by ssa.Function.DumpTo:
it makes it too hard to constructed expected outputs for tests.
(Tabs may appear at line start though.)
Sadly godoc -play won't run this program; it complains it
can't import "code.google.com/p/go.exp/ssa". Any idea why?

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.
