In a dynamic interface method call x.f() where x has type I, it is not sound
to assume that the receiver of the types.Signature for types.Func f has type I, as
Func objects for abstract methods may be shared by multiple interfaces.

"static" ignores dynamic calls altogether.
"cha" uses Class Hierarchy Analysis, which assumes that a
dynamic call may dispatch to any func or method that satisfies
the type.
Both these algorithms can work on partial programs,
e.g. libraries without a main function or tests.
(This feature was requested after my talk last night.)
