/// specialization to cope with MSVC (at least till 2015) where only an
/// integer literal can be used to specify an alignment constraint. Once built
/// up here, we can then begin to indirect between these using normal C++
/// template parameters.

// a member of a by-value function argument in MSVC, even if the alignment
// request is something reasonably like 8-byte or 16-byte. Note that we can't
// even include the declspec with the union that forces the alignment because
// MSVC warns on the existence of the declspec despite the union member forcing
