I'm working on a test harness to check our assembly correctly restores
callee-saved registers. It caught this.
While perlasm tries to smooth over the differences between Windows and SysV
ABIs, it does not capture the difference in xmm registers. All xmm registers
are volatile in SysV, while Windows makes xmm6 through xmm15 callee-saved.
