Timo 98555244f0 [PERF] Don't spawn so many compilers (3/2) (19m -> 250k) (#15030) ... Optimize `needless_doctest_main`, make it short-circuit, make sure that we don't spin up a new compiler on EVERY code block. --- The old implementation was creating a new compiler, new parser, new thread, new SessionGlobals, new everything for each code block. No matter if they actually didn't even contain `fn main()` or anything relevant. On callgrind, seems that we're reducing about a 6.7242% de cycle count (which turns out to be a 38 million instruction difference, great!). Benchmarked in `bumpalo-3.16.0`. Also on bumpalo we spawn 78 less threads. This moves `SessionGlobals::new` from the top time-consuming function by itself in some benchmarks, into one not even in the top 500. Also, populate the test files. changelog:[`needless_doctest_main`]: Avoid spawning so many threads in unnecessary circumstances		2025-06-20 21:58:45 +00:00
