Added ASSERT(!document.childNeedsDistributionRecalc) before using m_nodeToInsertionPoints.
Added ASSERT(!document.childNeedsDistributionRecalc) before using m_nodeToInsertionPoints.

We cannot use m_nodeToInsertionPoints when document.childNeedsDistributionRecalc() is true.

So added ASSERT to finalDestinationInsertionPointFor and destinationInsertionPointsFor.

BUG=338970,337618
TEST=no new test, because this patch just added two asserts.
