Log Message:
-----------
Separate debug info file issue fixed.
A DwarfFrameParser object was not being created in the case of separate
debug info file, because libdw does not create Dwarf handles to files
that contain only .eh_frame section without .debug_*. This was causing
AST variable node to assert because the local variables did not get
location list, since .eh_frame reference was never saved for lookup.
The solution was to create a DwarfFrameParser saving not only a possible
Dwarf handle but also an Elf reference, since the .eh_frame section will
be in the main stripped binary, while the Dwarf handle will point to
the separate debug file.

Functionality will be removed from GitHub.com on January 31st, 2019.
