Target-specific modular transformations have to be able to cope with
external libraries. Target-specific global transformations should be
optimizations, and not required for correctness, since a simple linker
may choose not to perform them.
Make mixin resolution modular by making it fail when a mixed-in class
comes from an external library. (We cannot mix in such a class because
we do not necessarily have all class members.)

Previously, we would generate a stub for a redirecting factory, but
the default parameter values were not correctly forwarded.
This could have been fixed by copying the default parameter values into
the stub, but this conflicts with modular compilation, since the
element model does not expose default parameter values, and we should
not rely on the AST of libraries not part of the current build unit.
Apart from fixing this bug, this is also more aligned with how all the
backends actually work.

The VM does not support function type parameters at the moment, but we
can erase them at the last minute, to enable testing of other parts of
strong mode.
This also disables error checking in the SDK since the VM's
patch files are not in strong mode.
