Don't use a SyntheticProvider for literally every type Replaces a glob regex with individualized imports for each standard library type. This improves debugger performance by quite a bit when populating lots of values with lots of fields With the glob, afaik every single value of every single type that the debugger renders is run through a python function that does quite a few string comparisons (i plan to fix those next) to determine the SyntheticProvider to use. It looks like DefaultSyntheticProvider's functions internally call the liblldb c++ functions, which ends up with identical behavior to not using a SyntheticProvider at all, except you have extra python round trips slowing things down. These sample vidoes were run on x86-64-pc-windows-gnu. `vect` is a 1000 element `Vec<Big>`, `Big` contains a dozen or so `Small`, and `Small` contains a dozen or so `[i32; 5]` Before: https://github.com/user-attachments/assets/07c31fe7-e126-4c2e-8ae9-cfe36e351d3f After: https://github.com/user-attachments/assets/6c0d1a45-1ffe-46de-95a0-5dbe59a173b5 --- try-job: aarch64-apple
