  Changed paths:
    M llvm/lib/DebugInfo/DWARF/DWARFContext.cpp

    A llvm/test/DebugInfo/AArch64/frame-loclistx.s

  Log Message:
  -----------
  llvm-symbolizer: support DW_FORM_loclistx locations.

Summary:
With -gdwarf-5 local variable locations are emitted as DW_FORM_loclistx
form instead of the regular DW_FORM_sec_offset. Teach
DWARFDie::getLocations to understand the new format and use it in
llvm-symbolizer "FRAME" command.
