[sv-bc] enums in packed arrays

At yesterday's SV-BC meeting, we modified the description of packed unions
in a way that allows enums as members of packed unions.  We also noted that
the LRM allows enums as members of packed structs.

Given this, it seems inconsistent that the LRM does not allow enums as
elements of packed arrays.  Shouldn't we change this also?
