non-vectorized case

The SLPVectorizer doesn't seem to ignore debug intrinsics when deciding what to
vectorize.  The attached files when compiled with opt -slp-vectorizer will
either produce a set of <2 x i64> loads and stores (the case with no debug
info) or a set of two i64 loads and stores (the case with debug info).
