Rollup merge of #107373 - michaelwoerister:dont-merge-vtables-when-debuginfo, r=WaffleLapkin
Don't merge vtables when full debuginfo is enabled. This PR makes the compiler not emit the `unnamed_addr` attribute for vtables when full debuginfo is enabled, so that they don't get merged even if they have the same contents. This allows debuggers to more reliably map from a dyn pointer to the self-type of a trait object by looking at the vtable's debuginfo. The PR only changes the behavior of the LLVM backend as other backends don't emit vtable debuginfo (as far as I can tell). The performance impact of this change should be small as [measured](https://github.com/rust-lang/rust/pull/103514#issuecomment-1290833854) in a previous PR.
