Arkady Shlykov 3dcaf296ae [Loop Peeling] Add possibility to enable peeling on loop nests. 
Summary:
Current peeling implementation bails out in case of loop nests.
The patch introduces a field in TargetTransformInfo structure that
certain targets can use to relax the constraints if it's
profitable (disabled by default).
Also additional option is added to enable peeling manually for
experimenting and testing purposes.
