gcc12-pr94589-wip.patch
Updated patch. This already does the optimizations, though needs testcase
coverage and perhaps something better for debug uses of the PHI_RESULT besides
the single non-debug use.
And, it won't work together with the above mentioned forwprop patch, I'm afraid
it would need to virtually undo that change but it would be hard.
