Description
This is important for types that are
dynamicstatically, but still contiguous at runtime. I haven't tested runtime gains yet, but I'm guessing it should have an impact (especially by taking #2809 as a model).The duplicated
!E1::contiguous_layoutlogic is to give compilers an easier time to evaluate theifas a constexpr, deleting the uncontiguous path for clearly statically contiguous layouts.
