cg_llvm: stop identifying ADTs in LLVM IR This is an extension of https://github.com/rust-lang/rust/pull/94107. It may be a minor perf win. Fixes #96242. Now that we use opaque pointers, ADTs can no longer be recursive, so we do not need to name them. Previously, this would be necessary if you had a struct like ```rs struct Foo(Box<Foo>, u64, u64); ``` which would be represented with something like ```ll %Foo = type { %Foo*, i64, i64 } ``` which is now just ```ll { ptr, i64, i64 } ``` r? `@tmiasko` |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
