precoloured nodes to degree 255. I would like to play hangman on the one
who removed that code.

* move some protected and private field around
* the temp. register for register parameters/arguments are now released
before the move to the parameter register is done. This improves
the code in a lot of cases.

be translated from virtual to normal registers. Requires support in
the assembler writer as well, which is only implemented in aggas/

statements: changes in location_force. These moves are now no longer
constrained so they are optimized away.
