[SLP] Add test case showing a bug when dealing with padded types

We shouldn't vectorize stores of non-packed types (i.e. types that
has padding between consecutive variables in a scalar layout,
but being packed in a vector layout).

The problem was detected as a miscompile in a downstream test case.

This is a pre-commit of a test case for the fix in D94446.
