Rollup merge of #137603 - davidtwco:extern-types-no-deref, r=lcnr
codegen_llvm: avoid `Deref` impls w/ extern type `rustc_codegen_llvm` relied on `Deref` impls where `Deref::Target` was or contained an extern type - in my experimental implementation of rust-lang/rfcs#3729, this isn't possible as the `Target` associated type's `?Sized` bound cannot be relaxed backwards compatibly (unless we come up with some way of doing this). In later pull requests with the rust-lang/rfcs#3729 implementation, breakage like this could only occur for nightly users relying on the `extern_types` feature. Upstreaming this to avoid needing to keep carrying this patch locally, and I think it'll necessarily need to change eventually.
