Jens Johansen 60029641af [analyzer] Train snapshot more than --help ... The analyzer snapshot is currently "trained" with `--help`, i.e. not really trained at all. Doing some archaeology, it actually used to be trained, but it was disabled in https://dart-review.git.corp.google.com/c/sdk/+/77228 because of Fuchsia issues (https://github.com/dart-lang/sdk/issues/34616). Although the troublesome stuff was perhaps fixed in https://dart-review.git.corp.google.com/c/sdk/+/77422 it was seemingly never re-enabled. That was 2018. This CL re-enables it, taking an initial uncached analysis of dart2js to ~51% (~9.5s vs ~18.6s), of the analyzer to ~75% (~22.2s vs ~29.6) and of the front_end to ~50% (~7.7s vs ~15.2s). This won’t change the peak performance of the analyzer, but will certainly - as seen above - make it faster when first loaded.
