Rollup merge of #132076 - RalfJung:feature-hashing, r=nnethercote,Mark-Simulacrum
HashStable for rustc_feature::Features: stop hashing compile-time constant It seems like back in https://github.com/rust-lang/rust/commit/542bc75deaaf4e84dcd7a196685bc1a1cb100d32 this was added as "hash the boolean value of each lang feature", but then in https://github.com/rust-lang/rust/commit/1487bd6a174f813967ffff6b3334b4fe296f1f30 this got split into first hashing a sequence of `bool`s (representing all the features) and then hashing all the feature names... but the list of feature names is a compile-time constant, so it seems entirely unnecessary to hash them?
