Enabling a tied feature should not enable the other feature automatically. This was fixed by something in rust-lang#128796, probably rust-lang#128221 or rust-lang#128679.
`rustc_codegen_llvm` and `rustc_codegen_gcc` duplicated logic for checking if tied target features were partially enabled. This commit consolidates these checks into `rustc_codegen_ssa` in the `codegen_fn_attrs` query, which also is run pre-monomorphisation for each function, which ensures that this check is run for unused functions, as would be expected.

…n, r=wesleywiser codegen_ssa: consolidate tied target checks Fixes rust-lang#105110. Fixes rust-lang#105111. `rustc_codegen_llvm` and `rustc_codegen_gcc` duplicated logic for checking if tied target features were partially enabled. This PR consolidates these checks into `rustc_codegen_ssa` in the `codegen_fn_attrs` query, which also is run pre-monomorphisation for each function, which ensures that this check is run for unused functions, as would be expected. Also adds a test confirming that enabling one tied feature doesn't imply another - the appropriate error for this was already being emitted. I did a bisect and narrowed it down to two patches it was likely to be - something in rust-lang#128796, probably rust-lang#128221 or rust-lang#128679.
