Overall result: ✅ improvements - no 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.

@rustbot rustbot removed the S-waiting-on-perf Status: Waiting on a perf run to be completed. label Feb 10, 2023
@nnethercote
Pre-intern some commonly used type variables.
6248bbb 
This requires some rearrangement of plumbing, such as adding
`mk_fresh_{,int_,float_}ty` and removing `mk_ty_infer`.
@nnethercote
Reduce direct mk_ty usage.
7a72560 
We use more specific `mk_*` functions in most places, might as well use
them as much as possible.
@nnethercote
Avoid interning empty tuples.

Optimize `mk_region`

PR rust-lang#107869 avoiding some interning under `mk_ty` by special-casing `Ty` variants with simple (integer) bodies. This PR does something similar for regions.
