Unrolled build for #145340
Rollup merge of #145340 - Kobzol:bootstrap-codegen-backend-check-split, r=jieyouxu Split codegen backend check step into two and don't run it with `x check compiler` This reduces the amount of work that is done during `x check compiler`. We still check both backends during `x check` by defaut, even if they are not in `rust.codegen-backends`, as just checking them shouldn't require expensive preparations, like building GCC. r? `@jieyouxu`
