…ogaloo, r=<try> Use new faster fxhash. This was implemented in rust-lang/rustc-hash#37 by Orson Peters and benchmarked in rust-lang#125133. r? `@ghost` `@bors` try `@rust-timer` queue

…try> Defid derive hash r? `@ghost` Built on-top of rust-lang#128323, to see if using new fxhash lets us eliminate DefId custom hashing. (prediction: this kills perf, as we'll hash 2 u32's instead of 1 u64)

…try> Swap defid fields Built on-top of rust-lang#128323, to see if using new fxhash means we don't need to be carefull about where in the DefId we place the entropy r? `@ghost`

Finished benchmarking commit (235c20a): comparison URL.

Overall result: ❌✅ regressions and improvements - ACTION NEEDED

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

@bors rollup=never
@rustbot label: -S-waiting-on-perf +perf-regression
