[xbyak] fix unordered map that wasn't actually wanting to be unordered (#3589)

It seems to be related to the fact multimap on xbyak doesn't properly work if it's unordered
It also seems to NOT play nice at all with unstable iterators (like those found on ankerl) - either we use boost or just let xbyak use normal std
