DWARF: Call set_indirect_string on DW_MACINFO_start_file
Since -gsplit-dwarf -g3 will output filename as indirect string, call
set_indirect_string on DW_MACINFO_start_file for -gsplit-dwarf -g3.

PR debug/79342
* dwarf2out.c (save_macinfo_strings): Call set_indirect_string
on DW_MACINFO_start_file for -gsplit-dwarf -g3.
gcc/testsuite/
PR debug/79342
* gcc.dg/pr79342.: New test.
