Fix error on some compiler configurations

Sergey was having compile errors here, I couldn't recreate them though. It actually seems weird that we have to include BLI_utildefines.h before BLI_listbase.h, since the latter one already includes the former. Don't want to bother much with such minor issues though, so let's just make all compilers happy ;)

Patch is by @sergey himself.

Cycles: Split ShaderData object and shader flags

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).
