cmd/guru: describe Go 1.8 aliases

Also:
- always display the value of a constant expr, whether query expr is a
  definition, a reference, or an alias.
- eliminate some go1.5 portability code.
- remove go1.8 fork of referrers; no changes are necessary
  since I decided not to treat aliases specially.
- add tests.

Tested with Go 1.6, Go 1.7, and tip (Go 1.8).
