Weld Proxies are not marked as synthectic classes

Weld proxy classes are not marked as synthetic, so dynamically created classes do not return true for isSynthetic(). Tested with 1.1.11.Final and 2.0.0.CR4, from what I could see it applies to both the 2.0.x and 1.1.x branches.

I just checked with 2.0.1-SNAPSHOT, and it seems the underlying org.jboss.classfilewriter.ClassFile does not provide means to mark a class as synthetic.

4.7.6 The Synthetic Attribute

The Synthetic attribute6 is a fixed-length attribute in the attributes table of ClassFile (§4.1), field_info (§4.5), and method_info (§4.6) structures. A class member that does not appear in the source code must be marked using a Synthetic attribute.
