Mixins with Generics
...
This change adds support for generics to mixins. It's not a particularly elegant
implementation, so I expect to change how it works internally in later checkins.
Also, there is still one aspect of the implementation that is incorrect. In the
case of typedef, the newly introduced name is not yet an alias for the
mixin application. Instead, the MA is a superclass of the typedef name. That
will need to be fixed in a later checkin. I don't want to make this change
bigger.

Remove support for interfaces.
...
For now, disable tests using obsolete syntax.
Tests disabled in this cl and in previous ones removing default factory classes

Fix for issue 6359 - Make snapshots platform independent.
...
The issue previously was that an instance size was stored a
size in bytes, similarly field offsets were stored as an offset
in bytes. This caused issues when generating the snapshot on
one platform and reading it on another platform.
The VM has been changed to store the instance size as a size in
words and the field offset as an offset in words.

Remove support for default factory classes.
...
For now, disable tests using obsolete syntax. More will get disabled as support
for interfaces is completely removed. We may then permanently remove some tests,
while updating and reenabling others whose purpose is not related to interfaces.

Add flag 'implements' to class, it is set anytime someone implements this class. This is a way to recognize implicit interfaces in order to improve class checks.
