- Deal with closures in generic functions by fixing the stenciling code
- Deal with instantiated function values (instantiated generic
functions that are not immediately called) during stenciling. This
requires changing the OFUNCINST node to an ONAME node for the
appropriately instantiated function. We do this in a second pass,
since this is uncommon, but requires editing the tree at multiple
levels.
- Check global assignments (as well as functions) for generic function
instantiations.
- Fix a bug in (*subst).typ where a generic type in a generic function
may definitely not use all the type args of the function, so we need
to translate the rparams of the type based on the tparams/targs of
the function.
- Added new test combine.go that tests out closures in generic
functions and instantiated function values.
- Added one new variant to the settable test.
- Enabling inlining functions with closures for -G=3. (For now, set
Ntype on closures in -G=3 mode to keep compatibility with later parts
of compiler, and allow inlining of functions with closures.)

- Create the stencil name using targ.Type.String(), which handles cases
where, for example, a type argument is a pointer to a named type,
etc. *obj.
- Set name.Def properly for a new stenciled func (have the symbol point
back to the associated function node). Will be required when exporting.
- Add missing copying of Func field when making copies of Name nodes.
(On purpose (it seems), Name nodes don't have a copy() function, so
we have to copy all the needed fields explicitly.)
- Deal with nil type in subster.node(), which is the type of the return
value for a function that doesn't return anything.
- Fix min to match standard want/go form, and add in float tests. Changed
Got -> got in bunch of other typeparam tests.
- Add new tests index.go, settable.go, and smallest.go (similar to
examples in the type param proposal), some of which need the above
changes.
