this is more a proof of concept to show that the register allocation
can be improved. This is the first simple example I found, albeit used
only in a few cases.

Benchmark under Win64:
3872 decicycles in a32, 32761 runs, 7 skips
2194 decicycles in a16, 32766 runs, 2 skips

3767 decicycles in a32, 32765 runs, 3 skips
2119 decicycles in a16, 32767 runs, 1 skips
