symbols: Change implementation details of DECLARE_OPTIONAL_REGION()
It seems that GCC's LTO doesn't like the way we implement DECLARE_OPTIONAL_REGION(). This patch changes it so that rather than having a normal DECLARE_REGION() in <symbols.h> and then an extra DECLARE_OPTIONAL_REGION() in the C file using it, you just say DECLARE_OPTIONAL_REGION() directly in <symbols.h> (in place and instead of the usual DECLARE_REGION()). This basically looks the same way in the resulting object file but somehow LTO seems to like it better.
