[PATCH][gdb/testsuite] Generate .debug_aranges entry for dummy CU

[Tom de Vries]

Hi,

A best practise for DWARF [1] is to generate .debug_aranges entries for CUs
even if they have no address range.

Generate .debug_arange entries for the dummy CUs added by the DWARF assembler.

Tested on x86_64-linux.

Any comments?

Thanks,
- Tom
