The pattern-match-checking code potentially prints out derived errors because it doesn't check for ty_err like the rest of the typechecker does. I have a branch that almost fixes this but I got distracted working on higher-priority bugs.

Avoid or_fun_call for const_fn with no args

Based on rust-lang#5682 by @lzutao

This avoids a subset of false positives, specifically those related to `const fn`s that take no arguments.
For the rest, a much more involved fix would be needed, see rust-lang/rust-clippy#5682 (comment).

So this does *not* solve rust-lang#5658

changelog: Avoid triggering [`or_fun_call`] with `const fn`s that take no arguments.

Fixes rust-lang#5886
