Rollup merge of #67889 - Zoxc:parallel-cgus, r=michaelwoerister
Compile some CGUs in parallel at the start of codegen This brings the compilation time for `syntex_syntax` from 11.542s to 10.453s with 6 threads in non-incremental debug mode. Just compiling `n` CGUs in parallel at the beginning of codegen seems sufficient to get rid of the staircase effect, at least for `syntex_syntax`. Based on https://github.com/rust-lang/rust/pull/67777. r? @michaelwoerister cc @alexcrichton @Mark-Simulacrum
