rubyx/test/risc/test_builder.rb
Torsten Ruger f798173a09 change to_risc and builtin code according to last commit
Wherever space was loaded to get to the next_message
we now load the Message factory.
Otherwise much the same, only the attribute is next_object, not next_message
The binary is growing with 1k objects per factory, so i had to fix (hack) arm to handle bigger constants
close #14
