Teach gcroot how to handle dynamically realigned frames

I'm playing with supporting custom stack map formats with statepoints.  While
doing so, I noticed that the existing implementation didn't indicate inherently
unsized frames.  This change essentially just ports the functionality that already
exists for the default StackMaps section to custom stackmaps.
