- Have to delay the extra transformation on methods invoked on a type
param, since the actual transformation (including path through
embedded fields) will depend on the instantiated type. I am currently
doing the transformation during the stencil substitution phase. We
probably should have a separate pass after noder2 and stenciling,
which drives the extra transformations that were in the old
typechecker.
- We handle method values (that are not called) and method calls. We
don't currently handle method expressions.
- Handle type substitution in function types, which is needed for
function args in generic functions.
- Added stringer.go and map.go tests, testing the above changes
(including constraints with embedded interfaces).

Disabled test/typeparam/fact.go for now as there's an issue
with stenciling.

- Handle generic function calling itself or another generic function in
stenciling. This is easy - after it is created, just scan an
instantiated generic function for function instantiations (that may
needed to be stenciled), just like non-generic functions. The types
in the function instantiation will already have been set by the
stenciling.
- Handle OTYPE nodes in subster.node() (allows for generic type
conversions).
- Eliminated some duplicated work in subster.typ().
- Added new test case fact.go that tests a generic function calling
itself, and simple generic type conversions.
- Cause an error if a generic function is to be exported (which we
don't handle yet).
- Fixed some suggested changes in the add.go test case that I missed in
the last review.

Allow full compilation and running of simple programs with generic
functions by stenciling on the fly the needed generic functions. Deal
with some simple derived types based on type params.
Include a few new typeparam tests min.go and add.go which involve
fully compiling and running simple generic code.

This change makes a first connection between the compiler and types2.
When the -G flag is provided, the compiler accepts code using type
parameters; with this change generic code is also type-checked (but
then compilation ends).

Providing the -G flag instructs the compiler to accept type parameters.
For now, the compiler only parses such files and then exits.
Added a new test directory (test/typeparam) and initial test case.
Port from dev.go2go branch.
