Subject: Improved x86-64 XMM register argument passing.

Also made XMM0-7 available for use as temporary registers, since they
are not used by the ABI. I'd like to do the same with RSI and RDI but
that's trickier since they can be used by gv() as temporary registers
and there isn't a way to disable that.
