Caroline Concatto 3c03635d53 [SVE][LoopVectorize] Add support for scalable vectorization of loops with vector reverse ... This patch adds support for reverse loop vectorization. It is possible to vectorize the following loop: ``` for (int i = n-1; i >= 0; --i) a[i] = b[i] + 1.0; ``` with fixed or scalable vector. The loop-vectorizer will use 'reverse' on the loads/stores to make sure the lanes themselves are also handled in the right order. This patch adds support for scalable vector on IRBuilder interface to create a reverse vector. The IR function CreateVectorReverse lowers to experimental.vector.reverse for scalable vector and keedp the original behavior for fixed vector using shuffle reverse.
