We don't usually reformat the test directory, but all of the files in
test/typeparam are syntactically valid. I suspect the misformattings
here are because developers aren't re-installing gofmt with
-tags=typeparams, not intentionally exercising non-standard
formatting.

interfaces
Up to this point, we were only handling typeparams that were converted
to empty or non-empty interfaces. But we have a dictionary entry for
each derived type (i.e. type derived from typeparams) as well. So, when
doing a conversion, look for the source type in both the type params and
derived types of the generic info, and then use the appropriate
dictionary entry.
Added some cases to ifaceconv.go (e.g. converting []T to an empty
interface).

This CL handles I(x) where I is an interface type and x has
typeparam type.

When converting from a type param to an interface, allow it if
the type bound implements that interface.
Query: some conversions go through this path, some use another path?
The test does
var i interface{foo()int} = x
but
i := (interface{foo()int})(x)
works at tip.
