I've been long bothered that the builtin .tupleof and our own
abstractions Fields and RepresentationTypeTuple in std.traits - all omit
the essential information of field offsets. That makes types that use
align() to have the same .tupleof, Fields, and RepresentationTypeTuple
even though they shouldn't.
The right answer is Layout a tuple of (offset, type) pairs describing
entirely the memory layout of a type. We need such for memory
allocation, garbage collection, serialization, and more.
The implementation turned out to be quite compact - 81 lines including a
compile-time mergesort. Destroy!

Could use the name for the field as well. At the minimum useful for
debugging purposes.
