You're patching the wrong place. See can_combine_p,
which can test for specific sources, rather than
cant_combine_insn_p which has no access to sources.

This has always worked for the other ports AFAIK so I don't think we should
disable it without evaluating the impact on them. If reload has so many
problems with x32, maybe more fundamental changes should be made to the x86
