* decl.c (gnat_to_gnu_entity) <case E_Array_Type>: When setting
the alignment on the GCC XUA array type, set TYPE_USER_ALIGN if
this is from an alignment clause on the GNAT entity.
* utils.c (create_field_decl): Rewrite the computation of DECL_ALIGN
to distinguish the case where we set it from the type's alignment.
When so, propagate TYPE_USER_ALIGN into DECL_USER_ALIGN to indicate
whether this alignment was set from an explicit alignment clause.
