Yeah, I get that, but I want to keep the code history as clean as
possible.

One other thing I noticed: the

+#ifdef COMPILER2
+  const int stub_size = Compile::MAX_stubs_size/2;
+#else
+  const int stub_size = LIR_Assembler::call_stub_size();
+#endif
+
+  address stub = start_a_stub(stub_size);

is an unnecessary complication.  I'm testing this:

  // Max stub size: alignment nop, ldr, br, emit_int64
  address stub = start_a_stub(3 * NativeInstruction::instruction_size + wordSize);
