Example test case


Annotations on struct fields are represented as calls to the
llvm.ptr.annotation intrinsic. However, these calls do not seem to be removed
before code generation because the following fatal error occurs in the backend:

"fatal error: error in backend: Cannot select: intrinsic %llvm.ptr.annotation"
