Detect calls that do not target a function's entrypoint (i.e, calls to runtime.duffzero and runtime.duffcopy) and instead step into them directly. StepInto sets a breakpoint past the called function's prologue and expects that continue will hit that breakpoint, but because the call is into the interior of the function (well past the prologue) this fails. Fixes #573
