dwarf_loclist_from_expr() translates DWARF
  location expression bytes into a Dwarf_Locdesc
  descriptor. The size for address related data is taken to be the default
  address size for the object being read.
Argument dbg should reference a DWARF debug context allocated using dwarf_init(3).
Argument bytes_in should point to an array of DWARF location expression bytes.
Argument bytes_len should specify the number of the location expression bytes to be translated.
Argument llbuf should point to a location which will be set to a pointer to a returned Dwarf_Locdesc descriptor.
Argument listlen should point to a location which will hold the number of the Dwarf_Locdesc descriptors returned. In this case it is always set to 1.
If argument err is not
    NULL, it will be used to store error information in
    case of an error.
Function dwarf_loclist_from_expr_a() is
    identical to function dwarf_loclist_from_expr(),
    except that it requires one additional argument
    addr_size, which specifies the address size to use
    when translating the location expression bytes.
Function dwarf_loclist_from_expr_b() is
    identical to function dwarf_loclist_from_expr_a()
    except that it requires two additional arguments for translating the
    location expression bytes. Argument offset_size
    specifies the offset size, and argument version
    specifies the DWARF version. These values are required to correctly
    translate the DW_OP_GNU_implicit_pointer opcode.
DW_DLA_LOC_BLOCK.DW_DLA_LOCDESC.DW_DLV_OK. In case
  of an error, they return DW_DLV_ERROR and set the
  argument err.
