Extended promote buffers to stack pass to support dynamically shaped allocas.
The conversion is limited by the rank of the underlying tensor.
An option is added to the pass to adjust the given rank.

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 index type does not have a bitsize and hence the size of corresponding allocations cannot be computed. Instead, the promotion pass now has an explicit option to specify the size of index.

Added optimization pass to convert heap-based allocs to stack-based allocas in
buffer placement. Added the corresponding test file.

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.
