This patch implements the .debug_rnglists section. We are able to
produce the .debug_rnglists section by the following syntax.

  debug_rnglists:
    - Format:              DWARF32 ## Optional
      Length:              0x1234  ## Optional
      Version:             5       ## Required
      AddressSize:         0x08    ## Optional
      SegmentSelectorSize: 0x00    ## Optional
      OffsetEntryCount:    2       ## Optional
      Offsets:             [1, 2]  ## Optional
      Lists:
        - Entries:
            - Operator: DW_RLE_base_address
              Values:   [ 0x1234 ]

The generated .debug_rnglists is verified by llvm-dwarfdump, except for
the operator DW_RLE_startx_endx, since llvm-dwarfdump doesn't support
it.
