MAINT: memcpy-based ~4x faster, typed shuffle.
Only for 1d-ndarrays exactly, as subtypes (e.g. masked arrays) may not
allow direct shuffle of the underlying buffer (in fact, the old
implementation destroyed the underlying values of masked arrays while
shuffling).
Also handles struct-containing-object 1d ndarrays properly.
See #6776 for an earlier, less general (but even faster: ~6x)
improvement attempt, #5514 for the original issue.
