I used the x32 ABI at a previous job, for an ARM-on-x86 emulation project. The x32 ABI outperformed both x86 and x86_64 for that purpose. It wasn't a huge margin, but it was enough to make us want to use it over x86_64.
I wish I still had the performance data for that, so this would be more than an anecdotal comment.
