Rollup merge of #131954 - the8472:bootstrap-parallel-git, r=Kobzol
shave 150ms off bootstrap This starts `git` commands inside `GitInfo`and the submodule updates in parallel. Git should already perform internal locking in cases where it needs to serialize a modification. ``` OLD Benchmark #1: ./x check core Time (mean ± σ): 608.7 ms ± 4.4 ms [User: 368.3 ms, System: 455.1 ms] Range (min … max): 602.3 ms … 618.8 ms 10 runs NEW Benchmark #1: ./x check core Time (mean ± σ): 462.8 ms ± 2.6 ms [User: 350.2 ms, System: 485.1 ms] Range (min … max): 457.5 ms … 465.6 ms 10 runs ``` This should help with the rust-analyzer setup which issues many individual `./x check` calls. There's more that could be done but these were the lowest-hanging fruits that I saw.
