Added target specific combine rules to fold blend intrinsics according to the following rules: 1) fold(blend A, A, Mask) -> A; 2) fold(blend A, B, <allZeros>) -> A; 3) fold(blend A, B, <allOnes>) -> B. Added two new tests to verify that the new folding rules work for all the optimized blend intrinsics. llvm-svn: 208895
