Fix expected results for clang-r399163 update.

llvm-objdump changed the format it uses for displaying assembly, so we
must also adapt all of the ART tests similarly, since they check for
exact matching output. llvm-dwarfdump has similarly changed its outputs,
so we adjust our expectations there too.
