Untested fix 1.

But DECL_SOURCE_FILE is not the main input file of the TU that contains it, if
e.g. a variable is defined in a header.
Can't you find the corresponding TRANSLATION_UNIT_DECL (see e.g. how
dwarf2out.c is_cxx now looks for that) and get the name from that?
And, the multiple ?s look just weird, (in_lto_p && something ? something :
main_input_filename); would be nicer.
