unimplemented macro calls are crashing rust-analyzer

[Nashenas88]

I've seen a lot of panics coming from rust-analyzer that stem from one of these two unimplemented macro calls:

chalk/chalk-solve/src/clauses.rs

Lines 80 to 81 in 8f28056

	TypeName::OpaqueType(_) => unimplemented!(),
	TypeName::AssociatedType(_) => unimplemented!(),

The backtrace points to

chalk/chalk-solve/src/clauses.rs

Line 117 in 8f28056

pub fn push_auto_trait_impls<I: Interner>(

but it calls the function linked above, which is likely inlined.
