30542e06 - Fix tbaa annotation on union selector bytes inside of structs (#54604)

Fix tbaa annotation on union selector bytes inside of structs (#54604) We currently cause a alias analysis contradiction by saying that the unionselbytes are on the stack, even if they are on a struct. LLVM is then able to figure out that we giving it a impossible alias situation (the object doesn't alias itself) and triggers UB. https://godbolt.org/z/ssEKMzsPf We may want to do a benchmarks run on this to see if anything too critical hasn't regressed.
