  [mlir][SCF] Avoid generating unnecessary div/rem operations during coalescing (#91562)

When coalescing is some of the loops are unit-trip we can avoid
generating div/rem instructions during delinearization. Ideally we could
use some thing like `affine.delinearize` to handle this but tthat causes
dependence issues.
