x86_64-xlate.pl: import fix(?) from upstream.

Browse Source 
This imports the changes to x86_64-xlate from upstream's
9c940446f614d1294fa197ffd4128206296b04da. It looks like it's a fix,
although it doesn't alter our generated asm at all. Either way, no point
in diverging from upstream on this point.
