[issue20399] Comparison of memoryview

[fin swimmer]

New submission from fin swimmer:

Comparison by using memoryview seems not to work completely.

This works:
>>> memoryview(bytearray(range(5))) != memoryview(bytearray(range(5)))
False
>>> memoryview(bytearray(range(5))) == memoryview(bytearray(range(5)))
True

But:
>>> memoryview(bytearray(range(5))) < memoryview(bytearray(range(5)))
Traceback (most recent call last):
  File "", line 1, in 
TypeError: unorderable types: memoryview() < memoryview()

So memoryview cannot be used as a key-value for sorting
