If you had a group as the first element of a struct, i.e.
<struct name="3DSTATE_CONSTANT_BODY" length="10">
<group count="4" start="0" size="16">
<field name="ReadLength" start="0" end="15" type="uint"/>
</group>
...
</struct>
we would get a group_offset of 0, causing create_field() to think the
field wasn't in a group, and fail to offset forward for successive array
elements. So we'd mark all the array elements as offset 0.
Using ctx->group->elem_size is a better check for "are we in a group?".
