Make -Cpasses= only apply to pre-link optimization
This change causes passes specified in -Cpasses= to be applied only during pre-link optimization, not during LTO. This avoids such passes running multiple times, which they may not be designed for. Fixes https://github.com/rust-lang/rust/issues/97713
