add comparison operators to must-use lint (under `fn_must_use` feature) Although RFC 1940 is about annotating functions with `#[must_use]`, a key part of the motivation was linting unused equality operators. (See https://github.com/rust-lang/rfcs/pull/1812#issuecomment-265695898—it seems to have not been clear to discussants at the time that marking the comparison methods as `must_use` would not give us the lints on comparison operators, at least in (what the present author understood as) the most straightforward implementation, as landed in #43728 (3645b062).) To rectify the situation, we here lint unused comparison operators as part of the unused-must-use lint (feature gated by the `fn_must_use` feature flag, which now arguably becomes a slight (tolerable in the opinion of the present author) misnomer). This is in the matter of #43302. cc @crumblingstatue |

NB: This crate is part of the Rust compiler. For an overview of the
compiler as a whole, see
the README.md file found in librustc.
The syntax crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), parser, pretty-printer,
lexer, macro expander, and utilities for traversing ASTs.
