Whitelists functions debugCall32 through debugCall65536 in runtime.debugCallCheck so that any instruction inside those functions is considered a safe point. This is useful for implementing nested function calls. For example when evaluating: f(g(x)) The debugger should: 1. initiate the call to 'f' until the entry point of 'f', 2. complete the call to 'g(x)' 3. copy the return value of 'g(x)' in the arguments of 'f' 4. complete the call to 'f' Similarly for: f().amethod() The debugger should initiate the call to '.amethod()', then initiate and complete the call to f(), copy the return value to the arguments of '.amethod()' and finish its call. However in this example, unlike the other example, it may be impossible to determine the entry point of '.amethod()' until after 'f()' is evaluated, which means that the call to 'f()' needs to be initiated while stopped inside a debugCall... function.
