@TIHan I'd suggest waiting for #81267 to make it in and then solve this in the way @EgorBo suggested in the issue:

My working (ugly) prototype for RyuJIT: EgorBo@9b1d149 (I believe it should be done the other way - I'd introduce a GT_SELECT/GT_CMOV operator so we can later use it for other cmov-based optimizations, e.g. remove branches)

It should be less specific/pattern matchy.

@jakobbotsch - Ok, I can wait.
