Default initialize InsertionSuccess


Give up folding an expression if one of the operands is being laid out.
This prevents hitting an infinite recursion when a fill size expression
refers to a later fragment since computing the offset of that fragment
would require laying out the fill fragment and thus computing its size
expression.
