One-Shot Bufferize correctly handles RaW conflicts around repetitive regions (loops). Specical handling is needed for parallel regions. These are a special kind of repetitive regions that can have additional RaW conflicts that would not be present if the regions would be executed sequentially.
Example:
```
%0 = bufferization.alloc_tensor()
scf.forall ... {
%1 = linalg.fill ins(...) outs(%0)
...
scf.forall.in_parallel {
tensor.parallel_insert_slice %1 into ...
}
}
```
A separate (private) buffer must be allocated for each iteration of the `scf.forall` loop.
This change adds a new interface method to `BufferizableOpInterface` to detect parallel regions. By default, regions are assumed to be sequential.
A buffer is privatized if an OpOperand bufferizes to a memory read inside a parallel region that is different from the parallel region where operand's value is defined.
