Add some documentation for the 64-bit syscall ABI, which doesn't seem

This attempts to documented existing practice. The only small
discrepancy is glibc clobbers not quite matching the kernel (e.g.,
xer, some vsyscalls trash cr1 whereas glibc only clobbers cr0). These
will be resolved after this document is merged.
