Changes:

- Rebase
- Format some code
- New test cases @not_vectorized_select_icmp_const_cmp_in_recurrence and @not_vectorized_select_icmp_cmp_in_recurrence in Transforms/LoopVectorize/iv-select-cmp.ll.
- Not allow the inclusion of cmp instructions in FindLast recurrence, as I mentioned in the pre-commit revision D157375 <https://reviews.llvm.org/D157375>. The examples are @not_vectorized_select_icmp_const_cmp_in_recurrence and @not_vectorized_select_icmp_cmp_in_recurrence in   Transforms/LoopVectorize/iv-select-cmp.ll.
