Unrolled build for rust-lang#123591

Rollup merge of rust-lang#123591 - Zalathar:useless-cast, r=cuviper

Remove unnecessary cast from `LLVMRustGetInstrProfIncrementIntrinsic`

(Noticed while reviewing rust-lang#123409.)

This particular cast appears to have been copied over from clang, but there are plenty of other call sites in clang that don't bother with a cast here, and it works fine without one.

For context, `llvm::Intrinsic::ID` is a typedef for `unsigned`, and `llvm::Intrinsic::instrprof_increment` is a member of `enum IndependentIntrinsics : unsigned`.

---

The formatting change in `unwrap(M)` is the result of manually running `clang-format` on this file, and then reverting all changes other than the ones affecting these lines.
