Auto merge of #94512 - RalfJung:sdiv-ub, r=oli-obk
Miri/CTFE: properly treat overflow in (signed) division/rem as UB To my surprise, it looks like LLVM treats overflow of signed div/rem as UB. From what I can tell, MIR `Div`/`Rem` directly lowers to the corresponding LLVM operation, so to make that correct we also have to consider these overflows UB in the CTFE/Miri interpreter engine. r? `@oli-obk`
