Preloading stuff is simply loading from the same DImode address, so I'd think
that EH_NOTE should be moved from the original insn to the new insn without
much problems.

Please note that on x86_32 split pass is later splitting DImode memory access
to two SImode loads, this looks somehow harder problem as far as EH notes are
concerned, as the one above.

I'm not versed in this area, so I'll leave the fix to someone else.
