SDIV/IDIV were originally introduced for R and M profile only and there the Thumb encodings of SDIV/IDIV are mandatory whereas the ARM ones are optional (and weren't initially defined at all). So if you're looking for CPUs with only the Thumb encodings I would try checking older R profile cores like the Cortex-R4.
