RFR: 7130476 - Remove use of #ifdef TRACE_DEFINE_KLASS_TRACE_ID from klass.hpp

[Rickard Bäckman]

Hi,

can I have some reviews for this change?
I decided to go with unused typedefs (thanks Keith) for the usages in 
the class definition and a do { } while (0) in the method definition.

The webrev:

Thanks
