[debuginfo-tests] r338424 - [DWARF] Change a test to ensure the creation of a __debug_ranges section.

[David Blaikie via llvm-commits]

I wonder if this is portable between ELF and MachO situations. (I
wonder/don't know if comma is valid in an ELF section name, for instance)

Maybe a single inline function would be more clearly portable? Not sure.
