InheritanceMethodDependencyCounter Inheritance Object

MethodDependencyCounter keeps track of the number of dependencies for "named registers" used across methods. Named registers are that are not necessarily limited to a single method. They are created by the compiler and passed on to methods. The compiler uses the results to reserve usages through RegisterPool, which can be removed each time a method has been compiled into the shader.
