* A better x86_64 register mapping, with more argument registers.
Now that we can handle using C argument registers as global registers,
extend the x86_64 register mapping. We now have 5 integer argument
registers, 4 float, and 2 double (all caller-saves). This results in a
reasonable speedup on x86_64.
