We started to run out of bits there, so now we separate flags which came from __object_flags and which are either runtime or coming from __shader_flags. Rule now is: SD_OBJECT_* flags are to be tested against new object_flags field of ShaderData, all the rest flags are to be tested against flags field of ShaderData. There should be no user-visible changes, and time difference should be minimal. In fact, from tests here can only see hardly measurable difference and sometimes the new code is somewhat faster (all within a noise floor, so hard to tell for sure).
