Dereference any array type before expanding root-level SSBO members

Browse Source 
If we don't do this then we get reflection output like so:

ArrayedBind[0].a.a: offset 0, type 1406, size 1, index 4, binding -1, stages 0
ArrayedBind[0].a.b: offset 4, type 1406, size 1, index 4, binding -1, stages 0
ArrayedBind[0].b.a: offset 4, type 1406, size 1, index 4, binding -1, stages 0
ArrayedBind[0].b.b: offset 8, type 1406, size 1, index 4, binding -1, stages 0
ArrayedBind[0].b: offset 4, type 1406, size 1, index 4, binding -1, stages 1

When the outer reflection loop that calls blowUpActiveAggregate incorrectly iterates over the struct members.
