[patch, libfortran, RFC] Speed up cshift with array shift


Hello world,

this is an RFC patch for speeding up the other part of cshift.
No mathematical tricks this time, just new functions which
copy the data types instead of using memcpy.

Performance improvement:

 cpu time cshift dim=1   0.277510017
 cpu time do loop dim=1   0.201206982
 cpu time cshift dim=2   0.514984965
 cpu time do loop dim=2   0.515266180
 cpu time cshift dim=3    1.01037502
 cpu time do loop dim=3    1.03989792

vs (gcc 7 without the patch).

 cpu time cshift dim=1   0.492732018
 cpu time do loop dim=1   0.188914001
 cpu time cshift dim=2   0.601395011
 cpu time do loop dim=2   0.462792039
 cpu time cshift dim=3   0.942433834
 cpu time do loop dim=3    1.07195783

for the attached test case. So, better if not quite the
performance of straightforward DO loops.

Still something to be gained for dim=1 by using
memcpy for blocks; planned before I submit.

Comments? Did I miss anything for correctness?

Regards

	Thomas
