Michael Zolotukhin 916731afee [SLP] Don't vectorize loads of non-packed types (like i1, i2). ... Summary: Given an array of i2 elements, 4 consecutive scalar loads will be lowered to i8-sized loads and thus will access 4 consecutive bytes in memory. If we vectorize these loads into a single <4 x i2> load, it'll access only 1 byte in memory. Hence, we should prohibit vectorization in such cases. PS: Initial patch was proposed by Arnold.
