error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.60.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: -C debuginfo=2

query stack during panic:
end of query stack

Rollup merge of rust-lang#94242 - compiler-errors:fat-uninhabitable-p…

…ointer, r=michaelwoerister

properly handle fat pointers to uninhabitable types

Calculate the pointee metadata size by using `tcx.struct_tail_erasing_lifetimes` instead of duplicating the logic in `fat_pointer_kind`. Open to alternatively suggestions on how to fix this.

Fixes rust-lang#94149
