Failed merges:

cg_llvm: Use an invariant lifetime brand for LLVM attributes #165861 (cg_llvm: Use an invariant lifetime brand for LLVM attributes)

after some discussion, we decided we want view types to be `!Sized`, at least at the beginning. this commit updates the test suite so that view types are not passed by value anymore.

this commit is quite big because we want to always exhaustively match on all the `TyKind` variants. none of the `unimplemented!()` is reachable because we don't *actually* lower view types (yet!).

/!\ the test suite is has not been updated /!\ the `unreachable!()`s added previously are suddenly reached, triggering literally all the view types test suite to ICE. this is fixed by the next commit.

By default, we optimize cargo and thus need to run the stage2 PGO-instrumented cargo binary to get its profiles. When we opt out of that, we don't have a stage2 cargo, and don't need it, so we just use the regular stage0 cargo there.
