[vsipl++] [patch] Add byte-swapping support to save/load_view.hpp

[Don McCoy]

There were two problems with the previous version of this patch.  First,
the save_view function was reversing the bytes in the view in-place. 
This has been fixed by forcing it to copy the view so as to avoid this
problem.  Second, complex values were being handled incorrectly, i.e.
for complex floats, the entire 8-byte quantity was being swapped leading
to the reversal of the imaginary and real components.  The correct
operation is to perform two, four-bytes swaps.

Regression tests for the above were added.

Regards,
