hir_typecheck errors with some crates: `BUG:src/hir_typeck/*.cpp: TODO`

[barracuda156]

@thepowersgang @catap Can something be done about these (without much effort on your side) or related crates are just broken with mrustc? Given dependency hell, I will probably keep hitting the same broken deps LOL

Example 1:

@thepowersgang Should these kind of issues be reported by the way?

(I have no idea how to fix this and even what fails specifically.)

BUG/TODO suggests it is relevant, but this happens when building crates, which is kinda unsupported, at least officially.
