I think this should be rediscussed. I'm trying to fix PR14179 where we build a
CONSTRUCTOR for 8 million of initializers. It is unfortunate to be forced to
store a progressive INTEGER_CST into the TREE_PURPOSE of each element because
it would waste too much memory.
I know we used to accept a CONSTRUCTOR with empty TREE_PURPOSE pre-tree-ssa,
with the obvious meaning (previous index + 1). Why cannot we do this anymore?
