/* Compile with:
clang -g -c odr-uniquing.cpp -o odr-uniquing/1.o
cp odr-uniquing/1.o odr-uniquing/2.o
The aim of these test is to check that all the 'type types' that
should be uniqued through the ODR really are.
The resulting object file is linked against itself using a fake
debug map. The end result is:
- with ODR uniquing: all types (expect for the union for now) in
the second CU should point back to the types of the first CU.
- without ODR uniquing: all types are re-emited in the second CU
