Karthik Bhat e637d65af3 Allow vectorization of division by uniform power of 2. ... This patch adds support to recognize division by uniform power of 2 and modifies the cost table to vectorize division by uniform power of 2 whenever possible. Updates Cost model for Loop and SLP Vectorizer.The cost table is currently only updated for X86 backend. Thanks to Hal, Andrea, Sanjay for the review.
