Fix side effects for LLVM integer operations (udiv, sdiv) incorrectly marked as Pure (#166648)
This MR modifies side effect traits of some integer arithmetic
operations in the LLVM dialect.
Prior to this MR, the LLVM dialect `sdiv` and `udiv` operations were
marked as `Pure` through `tblgen` inheritance of the
`LLVM_ArithmeticOpBase` class. The `Pure` trait allowed incorrect
hoisting of `sdiv`/`udiv` operations by the
`loop-independent-code-motion` pass.
This MR modifies the `sdiv` and `udiv` LLVM operations to have traits
and code motion behavior identical to their counterparts in the `arith`
dialect, which were established by the commit/review below.
