Subject: debug/111409 - don't generate COMDAT macro sections for split DWARF

Split DWARF files aren't processed by the linker, so DW_MACRO_import
offsets aren't relocated and the .debug_macro.dwo sections aren't
deduplicated and merged.  There's no clear way for this to work for
split DWARF, so disable it.

gcc/ChangeLog:

	PR debug/111409
	* dwarf2out.cc (output_macinfo): Don't call optimize_macinfo_range if
	dwarf_split_debug_info.

gcc/testsuite/ChangeLog:

	PR debug/111409
	* gcc.dg/pr111409.c: New test.
