ARM 3.6.2(11) "An implementation should normally represent a
multidimensional array in row-major order, consistent with the notation
used for multidimensional array aggregates (see 4.3.3). However, if a
Pragma Convention(Fortran, ...) applies to a multidimensional array type,
then column-major order should be used instead ..."
It would be strange to include powerful rep spec capabilities to define
everything about layouts, but not how an array is stored.
