It's just a waste of memory. This also gets rid of the special case for

Revisions asked by eddyb :
- Renamed of all the occurences of {visit/super}_mir
- Renamed test structures `CachedMir` to `Cached`

Fixing the missing import on `AggregateKind`
Changes the type `mir::Mir` into `mir::Body`

Fixes part 1 of rust-lang#60229 (previously attempted in rust-lang#60242).

I stumbled upon the issue and it seems that the previous attempt at solving it was not merged. This is a second try more up-to-date.

PGO - Add a smoketest for combining PGO with cross-language LTO.

This PR

- Adds a test making sure that PGO can be combined with cross-language LTO.
- Does a little cleanup on how the `pgo-use` flag is handled internally.
- Makes the compiler error if the `pgo-use` file given to `rustc` doesn't actually exist. LLVM only gives a warning and then just doesn't do PGO. Clang, on the other hand, does give an error in this case.
- Makes the build system also build `compiler-rt` when building LLDB. This way the Clang compiler that we get from building LLDB can perform PGO, which is something that the new test case wants to do. CI compile times shouldn't be affected too much.

Ship profiler with windows-gnu

Fixes rust-lang#49409

I don't know if we can enable it for testing, windows-gnu jobs are already taking too long: rust-lang#59637.
