collecting liveness information and in a backward pass on the
same list performs the actual register allocation, inserting
the instructions needed to spill values, if necessary.

+ The cross-platform local register allocator is now implemented
+ and it is documented in the jit-regalloc file.
When this part of code is implemented, some testing can be
done with the generated code for the new architecture. Most
tests. Also, using multiple -v switches on the command line
makes the JIT dump an increasing amount of information during
compilation.

+ *) 32 bit floats are extended to double precision (in particular
+ this means that currently all the floating point operations operate
