ad269dedd4 * If ds_dwarf_cpp (C++ emulation) is enabled, add DW_AT_linkage_name attribute for methods. 
LLDB uses it to display fully qualified method names. Add a simple C++ mangled name without params to achieve at least "Class::Method()" instead of just "Method" in LLDB.

f0d42db82d * When ds_dwarf_cpp option is enabled, use dwarf2 implementation of strings debug info. It makes LLDB happy.

6bd99b65bf + emit DW_AT_frame_base dwarf attributes on i8086. Even though the Watcom 
Debugger doesn't require them (it uses BP as the frame register by default),
  the dwarf spec requires that we emit them on i8086, because we also use
  DW_OP_fbreg on i8086.

c5fe78201c + emit DW_OP_bregx dwarf ops for local variables and parameters, relative to BP 
on i8086. This fixes Watcom Debugger not showing them right in memory models,
  where DS<>SS (Watcom seems to ignore the DW_AT_segment attribute for register
  relative variables, even though we emit it correctly :/ )

d1cdd8be7c * do not emit padding bytes after the dwarf arange header on i8086 for 
compatibility with Open Watcom (also, the dwarf spec is not very clear about
  the alignment requirements on segmented architectures, so that's why we do
  this by default, instead of putting it behind a -go debug switch)

600b460ecd + added new debug output option -godwarfomflinnum for generating line number 
information in OMF LINNUM records, in addition to the DWARF debug information.
  This enables source level debugging on i8086-msdos, when using the Open Watcom
  Debugger, provided the source was compiled with this option and the external
  linker (wlink) was used for generating the executable (the internal linker
  does not yet support generating debug information).
