Resynthesize typedef types properly from kernel.

I broke this functionality when I refactored FunctionTypeImpl into
lazy and strict variants; this CL restores it and simplifies it.

This CL also adds a new method to the analyzer API:
FunctionTypeAliasElement.instantiate(), to allow a client to supply
type arguments to a typedef (as one would at a site where the typedef
is used), to produce a type.  Putting the method in
FunctionTypeAliasElement helps move us toward an API that
distinguishes type "constructors" from types (a generic typedef
defines not just one type but a family of types; to obtain a type one
must instantiate the typedef by supplying type arguments).
