Add a check if regions do not implement the RegionBranchOpInterface. This is not
allowed in the current deallocation steps. Furthermore, we handle edge-cases,
where a single region is attached and the parent operation has no results.

getDynOperands behavior is commonly used in a number of passes. Refactored to
use a helper function and avoid code reuse.

These utilities are more closely associated with the buffer
optimizations and buffer deallocation than with the dialect conversion
stuff in Bufferize.h. So move them out.
This makes Bufferize.h very easy to understand and completely focused on
dialect conversion.

The current BufferPlacement transformation contains several concepts for
hoisting allocations. However, more advanced hoisting techniques should not be
integrated into the BufferPlacement transformation. Hence, this CL refactors the
current BufferPlacement pass into three separate pieces: BufferDeallocation and
BufferAllocation(Loop)Hoisting. Moreover, it extends the hoisting functionality
by allowing to move allocations out of loops.
