instead of DW_ELE_start_length in debug_rnglists section This patch tries to reduce the size of the debug_rnglist section by replacing the DW_RLE_start_length opcodes currently emitted by dsymutil in favor of using DW_RLE_base_addressx + DW_RLE_offset_pair instead. The DW_RLE_start_length is one AddressSize followed by a ULEB per entry, whereas, the DW_RLE_base_addressx + DW_RLE_offset_pair will use one ULEB for the base address, and then the DW_RLE_offset_pair is a pair of ULEBs. This will be more efficient. Differential Revision: https://reviews.llvm.org/D156166 (cherry picked from commit b66b176)
