Rollup merge of #133663 - scottmcm:carrying_mul_add, r=Amanieu
Add a compiler intrinsic to back `bigint_helper_methods` cc https://github.com/rust-lang/rust/issues/85532 This adds a new `carrying_mul_add` intrinsic, to implement `wide_mul` and `carrying_mul`. It has fallback MIR for all types -- including `u128`, which isn't currently supported on nightly -- so that it'll continue to work on all backends, including CTFE. Then it's overridden in `cg_llvm` to use wider intermediate types, including `i256` for `u128::carrying_mul`.
