Hans-Kristian Arntzen d1479f871a MSL: Do not generate UnsafeArray<> for any array inside buffer objects.
This avoids a lot of huge code changes.
Arrays generally cannot be copied in and out of buffers, at least no
compiler frontend seems to do it.

Also avoids a lot of issues surrounding packed vectors and matrices.
