This is in preparation to moving the hflags code into its own file
under the tcg/ directory.

I extracted these into a separate patch so we can discuss. If I move
the tcg_enabled check to a header that would add overhead for all the
calls where we know for sure that the code is running with TCG. And I
don't think we want a new arm_rebuild_hflags_foo to be used for common
code.
