Auto merge of #46253 - eddyb:return-aliasing, r=nagisa
rustc_trans: don't apply noalias on returned references. In #45225 frozen returned `&T` were accidentally maked `noalias`, unlike `&mut T`. Return value `noalias` is only sound for functions that return dynamic allocations, e.g. `Box`, and using it on anything else can lead to miscompilation, as LLVM assumes certain usage patterns. Fixes #46239.
