This patch adds the struct as a parameter to various functions. The struct is cached in ReflowInput so that we don't need to pass it down to the internal method where nsIFrame::ComputeSize() is called. In the subsequent patches, we'll use it to revise the implementation of flex container's flex base size resolution, and size overrides.
