* fixed alignment of bitpacked arrays of ordinals/enums: the prevous code

Browse Source 
always returned the alignment of enum/ordinal by itself, which could be
    either bigger or smaller than what was required
  * for non-bitpacked regular arrays, always use the alignment of the elements
    instead of sometimes the natural alignment of the size of the elements
    (which can be different)
