rail feee45c872 Fix the ICE 6539
It happened because `zero_sized_map_values` used `layout_of` with types
from type aliases, which is essentially the same as the ICE 4968.

// The test for the ICE 6539: https://github.com/rust-lang/rust-clippy/issues/6539.
// The cause is that `zero_sized_map_values` used `layout_of` with types from type aliases,
// which is essentially the same as the ICE 4968.
// Note that only type aliases with associated types caused the crash this time,
// not others such as trait impls.
