Rollup merge of #58975 - jtdowney:iter_arith_traits_option, r=dtolnay

Implement `iter::Sum` and `iter::Product` for `Option`

This is similar to the existing implementation for `Result`. It will take each item into the accumulator unless a `None` is returned.

I based a lot of this on #38580. From that discussion it didn't seem like this addition would be too controversial or difficult. One thing I still don't understand is picking the values for the `stable` attribute. This is my first non-documentation PR for rust so I am open to any feedback on improvements.

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.

have tested locally.

It makes sense, though---`\` followed by LF would eat it, so we'd have
`sysroot done` instead of `sysroot; done` as it is parsed.  This should
