2020-09-08 Triage Log

See the README for details on how this log was gathered.

A few small compile-time regressions this week. The first was #70793, which added some specializations to the standard library in order to increase runtime performance. The second was #73996, which adds an option to the diagnostics code to print only the names of types and traits when they are unique instead of the whole path. The third was #75200, which refactored part of BTreeMap to avoid aliasing mutable references.
