The new implementation allows some `memcpy`s to be optimized away, so the uninit value in ui/sanitize/memory.rs is constructed directly onto the return place. Therefore the sanitizer now says that the value is allocated by `main` rather than `random`.

Introduce NullOp::AlignOf This PR introduces `Rvalue::NullaryOp(NullOp::AlignOf, ty)`, which will be lowered from `align_of`, similar to `size_of` lowering to `Rvalue::NullaryOp(NullOp::SizeOf, ty)`. The changes are originally part of rust-lang#88700 but since it's not dependent on other changes and could have performance impact on its own, it's separated into its own PR.
