Alan Donovan 3371b79a96 go.tools/pointer: reflect, part 2: channels.
(reflect.Value).Send
        (reflect.Value).TrySend
        (reflect.Value).Recv
        (reflect.Value).TryRecv
        (reflect.Type).ChanOf
        (reflect.Type).In
        (reflect.Type).Out
        reflect.Indirect
        reflect.MakeChan

Also:
- specialize genInvoke when the receiver is a reflect.Type under the
  assumption that there's only one possible concrete type.  This
  makes all reflect.Type operations context-sensitive since the calls
  are no longer dynamic.
- Rename all variables to match the actual parameter names used in
  the reflect API.
- Add pointer.Config.Reflection flag
  (exposed in oracle as --reflect, default false) to enable reflection.
  It currently adds about 20% running time.  I'll make it true after
  the presolver is implemented.
- Simplified worklist datatype and solver main loop slightly
  (~10% speed improvement).
- Use addLabel() utility to add a label to a PTS.

(Working on my 3 yr old 2x2GHz+4GB Mac vs 8x4GHz+24GB workstation,
one really notices the cost of pointer analysis.
Note to self: time to implement presolver.)
