[RFC/dwarf-2] Add support for included files

[Andrew Pinski]

I try to test building gdb with the mainline of gcc and it fails
to compile with the following error:

/home/gates/pinskia/src/gnu/combinesources/src/gdb/dwarf2read.c: In 
function `dwarf2_create_include_psymtab':
/home/gates/pinskia/src/gnu/combinesources/src/gdb/dwarf2read.c:1244: 
error: invalid lvalue in assignment

Could you fix the problem, please?

Thanks,
Andrew Pinski
