shkzhang 4e9778e346 [CodeGen] [ExpandReduction] Fix the bug for ExpandReduction() when vector size isn't power of 2 
Summary:
For below test case, we will get assert error except for AArch64 and ARM:

declare i8 @llvm.experimental.vector.reduce.and.i8.v3i8(<3 x i8> %a)
define i8 @test_v3i8(<3 x i8> %a) nounwind {
  %b = call i8 @llvm.experimental.vector.reduce.and.i8.v3i8(<3 x i8> %a)
  ret i8 %b
}
In the function getShuffleReduction (), we can see it needs the vector size must be power of 2.

This patch is fix below error when the number of element is not power of 2 for those llvm.experimental.vector.reduce.* function.
