RFR: 8201217: Split specialized_oop_closures.hpp into GC specific files

[Erik Österlund]

Hi StefanK,

I'm guessing the SPECIALIZED_OOP_OOP_ITERATE_CLOSURES_1 vs 
SPECIALIZED_OOP_OOP_ITERATE_CLOSURES_2 distinction can be removed 
assuming that the MSVC problems that motivated their introduction is 
gone today. Same goes for how 
PromotionInfo::promoted_oops_iterate##nv_suffix is generated with 
SPECIALIZED_SINCE_SAVE_MARKS_CLOSURES_YOUNG as a workaround for the same 
problem as described in a comment in promotionInfo.cpp. But that seems 
like going beyond the intended scope of this change.

Looks good.

Thanks,
/Erik
