CL https://golang.org/cl/66130 changes go/printer to format one-method
interfaces to be printed on a single line. This change broke the
equality check in TestRewrites. Fix it by reformatting the expected
file buffers so that the tests pass with tip and previous Go versions.

Attempt to update doc comments when renaming an identifier.
This reduces the amount of manual steps that need to be taken
when using gorename.
All occurrences of the old identifier are updated in the doc.
The update is done using a regex to ensure that we replace
whole word matches only.

Because go/types is slightly more strict than gc about certain "soft"
errors (ones that aren't necessary to interpret a Go program), gorename
rejects programs that compile under gc. This change relaxes gorename's
error checks so that they are weaker than gc's.
This is a workaround for issue golang/go#14596 in gorename,
whose underlying problem is issue golang/go#8560 in gc.

This refactoring of the tests of go/loader and refactor/rename made it
possible to write some loader tests I wanted, but the new tests reveal
bugs so they're commented out for now. I will fix them in a follow-up.

This change adds a command mvpkg that will move a given package and
update all its imports. It uses similar logic to gorename to update
the imports.

Previously, gorename rejected all method renamings if it would
change the assignability relation.
Now, so long as the renaming was initiated at an abstract
method, the renaming proceeds, changing concrete methods (and
possibly other abstract methods) as needed. The user
intention is clear.
The intention of a renaming initiated at a concrete method is
less clear, so we still reject it if it would change the
assignability relation. The diagnostic advises the user to
rename the abstract method if that was the intention.
Additional safety checks are required: for each
satisfy.Constraint that couples a concrete type C and an
interface type I, we must treat it just like a set of implicit
selections C.f, one per abstract method f of I, and ensure the
selections' meanings are unchanged.
The satisfy package no longer canonicalizes types, since this
substitutes one interface for another (equivalent) one, which
is sound, but makes the type names random and the error
messages confusing.
Also, fixed a bug in 'satisfy' relating to map keys.
+ Lots more tests.

Also, allow but don't require parens and stars.
e.g. (*"encoding/json".Decoder).Decode or "encoding/json".Decoder.Decode
but not encoding/json.Decoder.Decode.
Since -from queries are now Go expressions, we use the Go parser.

See the usage message in main.go for orientation.
To the best of my knowledge, the tool implements all required
soundness checks, except:
- the dynamic behaviour of reflection is obviously undecidable.
- it rejects method renamings that change the "implements" relation.
It should probably be more aggressive.
- actually it only checks the part of the "implements" relation
needed for compilation. Understanding the dynamic behaviour
of interfaces is obviously undecidable.
- a couple of minor gaps are indicated by TODO comments.
Also:
- Emacs integration.
- tests of all safety checks and (some) successful rewrites.
