[LoopVectorize] Vectorize select-cmp reduction pattern for increasing integer induction variable (#67812)
Consider the following loop:
```
int rdx = init;
for (int i = 0; i < n; ++i)
rdx
[LoopVectorize] Vectorize select-cmp reduction pattern for increasing integer induction variable (#67812)
Consider the following loop:
```
int rdx = init;
for (int i = 0; i < n; ++i)
rdx = (a[i] > b[i]) ? i : rdx;
```
We can vectorize this loop if `i` is an increasing induction variable.
The final reduced value will be the maximum of `i` that the condition
`a[i] > b[i]` is satisfied, or the start value `init`.
This patch added new RecurKind enums - IFindLastIV and FFindLastIV.
