Auto merge of #51165 - SimonSapin:opt2, r=alexcrichton 

Revert "Set opt-level to 3"

This reverts commit aad9840ad4.

Level 3 (possibly indirectly, the underlying bug might be in XCode’s linker) causes unit tests to sefault when compiled with some versions of XCode: https://github.com/rust-lang/rust/issues/50867

It also appears to cause some segfaults on Windows: https://github.com/rust-lang/rust/pull/50329#issuecomment-386853473, and regressions in some rustc performance benchmarks: https://github.com/rust-lang/rust/pull/50329#issuecomment-388084894
