Method TypeDataChanged

IDEHelper/Compiler/BfContext.cpp:1404–1498

Dependencies cascade as such: DerivedFrom / StructMemberData: these change the layout of memory for the dependent classes, so not only do the dependent classes need to be rebuild, but any other classes relying on those derived classes (either by derivation, containment, or field reading) need to have their code recompiled as well. ReadFields: when ClassB depends on the data layout of ClassA, and C

//   (obviously) doesn't change the data layout of ClassC
//  Calls: non-cascading dependency, since it's independent of data layout ConstValue: non-cascading data change
