Bug 1546223 Part 5 - Change ReflowInput::InitConstraints() to use Maybe for containing block size. r=dholbert There are some minor behavior changes come with this. 1) Change the default containing block size to (NS_UNCONSTRAINEDSIZE, NS_UNCONSTRAINEDSIZE). I think this is more reasonable than (-1, -1). 2) mContainingBlockSize is used to cache only the block size passing though constructor, Init(), or the invalid (-1, -1). This patch makes it cache the value computed by ComputeContainingBlockRectangle(). Note that mContainingBlockSize is used only in nsTableWrapperFrame::InitChildReflowInput() to set the inner table frame's containing block to be the same as the outer table frame's. We don't change this behavior by caching more. Because even if the inner frame use the invalid cached (-1, -1) containing block size from the outer reflow input, it still computes the block size again in InitConstraints(). (Inner table's cb is the same as the outer table's per InitCBReflowInput().) Differential Revision: https://phabricator.services.mozilla.com/D28586
