6c7e4c0fe2 stop pinning self and frame
before: r0-message , r1-self , r2-frame , r3-new_message , r4 + tmps
now: r0-message , r1-new_message , r2 + tmps
programs got smaller, less fuss
also fix in return implementation that got the address from the wrong
message

Torsten Ruger
f4a4ccb98e several larger changes came together, bit of cleaning too
- all code must be in functions (which must be in classes).
— changes a fair few tests
— also changes api, as method is not recursive, not passed around
- all state in instance vars in compiler (no accessors)
- class is another such variable, surely more coming
all green again
