Auto merge of #46428 - eddyb:scalar-pair-unpacking, r=arielb1
rustc: don't unpack newtypes of scalar-pairs with mismatched alignment.

This PR fixes a potential problem where a packed newtype of a pair was also considered a pair, even though it didn't have the required alignment of the pair.
cc @oli-obk It's possible miri hit something like this, with an unstable feature, but it's more general.
