Cc rust-lang#113549

No functional changes intended.

Adds an include for llvm::SmallString. Previously, this must have been
implicitly provided by some of the existing headers. With recent LLVM
changes, not anymore:

The commit llvm/llvm-project@53717ca
removed the flag from LLVM.

remove compile-flags that are no longer needed

We stopped running fail-tests with optimizations a while ago, so we don't need to explicitly set the opt-level to 0 any more.

Use maybe_body_owned_by for multiple suggestions

This is a continued work from rust-lang#113567

We have several other suggestions not working for closure, this PR use `maybe_body_owned_by` to fix them and add test cases for them.

Rename VecDeque's `rotate_left` and `rotate_right` parameters

This pull request introduces a modification to the `VecDeque` collection, specifically the `rotate_left` and `rotate_right` functions, by renaming the parameter associated with these functions.

The rationale behind this change is to provide clearer and more consistent naming for the parameter that specifies the number of places to rotate the double-ended queue. By using `n` as the parameter name in both functions, it becomes easier to understand and remember the purpose of the parameter.

Print artifact sizes in `opt-dist`

The Python PGO script printed a nice table of artifact sizes (`librustc_driver.so`, `libLLVM.so`, ...) at the end of the CI run, which was useful to quickly see the sizes of important files. I forgot to port this functionality into the Rust (`opt-dist`) version in rust-lang#112235. This PR fixes that.

llvm-wrapper: update for LLVM API change

No functional changes intended.

tests: adapt for removal of -opaque-pointers in LLVM 17

Make it clearer that we're just checking for an RPITIT

Tiny nit to use `is_impl_trait_in_trait` more, to make it clearer that we're just checking whether a def-id is an RPITIT, rather than doing something meaningful with the `opt_rpitit_info`.

This fixes a pretty nasty bug in the tag GC.
