-- In existing design memory pool supports buffers of only one
size, This size is determined at compile time to support buffer
needed for biggest block size and data type. However, the size
calculation is not generic as it considers sizes only for GEMM.
Also it assumes that the buffer will not be used for any other
purpose than packing operations.
-- If the new buffer is requested whose size is bigger than existing
size, The pool is re-initialized to contain buffers of new size,
however, this is done only if the pool is empty. If the pool is not
empty the execution is aborted. This is undesirable as in
mulithreaded scenarios it is possible that different threads needs
buffers of different sizes at the same time (i.e. while other thread
is still in middle of the operation).
-- This commit removes the restriction of single size buffer, when
new buffer is requested whose size if bigger than exiting one, no
re-init is done. New buffer of required size is allocated, added
to the pool and returned to the user.
