Matthew Simpson bdd1452784 [SLP] Vectorize the index computations of getelementptr instructions. ... This patch seeds the SLP vectorizer with getelementptr indices. The primary motivation in doing so is to vectorize gather-like idioms beginning with consecutive loads (e.g., g[a[0] - b[0]] + g[a[1] - b[1]] + ...). While these cases could be vectorized with a top-down phase, seeding the existing bottom-up phase with the index computations avoids the complexity, compile-time, and phase ordering issues associated with a full top-down pass. Only bundles of single-index getelementptrs with non-constant differences are considered for vectorization.
