[PATCH] D30086: Add generic IR vector reductions

Renato and I discussed this offline for a bit because we got our wires crossed a bit before. We agreed to simplify this code a bit more by extending `createSimpleTargetReduction()` to handle min/max by passing it the ReductionFlags. This essentially moves code from `createTargetReduction()` making it now just unwrap information from a RecurrenceDescriptor. Some other API changes done as a result.
