I don't know where initialized DECL_COMMON could come from, but this spot
certainly isn't the only one that is counting with that, e.g. when deciding
what section to use comm_section is used only if it is bbs_initializer_p, etc.
At least for GCC 5, I'd strongly prefer small provably correct changes at this
point.
