Revert r303159 "[DWARF] - Use DWARFAddressRange struct instead of uint64_t pair for DWARFAddressRangesVector."
Something went wrong, it broke BB. http://green.lab.llvm.org/green//job/clang-stage1-cmake-RA-incremental_build/38477/consoleFull#-200034420049ba4694-19c4-4d7e-bec5-911270d8a58c llvm-svn: 303162
