Fredrik Holmqvist f133d007f9 Upgrade GMP from 5.0.5 to 6.1.2 (2016-12-16) 
Old version was from 2012-05-06, 6.1.2 is from 2016-12-16
A lot of support for newer processors and speedups since then
See gmp/NEWS for details

C TODO
C * Consider using special code for small n, using something like
C "switch (8 * (n >= 8) + (n mod 8))" to enter it and feed-in code.
C * The non-nc code was trimmed cycle for cycle to its current state. It is
C probably hard to save more that an odd cycle there. The nc code is much
C cruder (since tune/speed doesn't have any applicable direct measurements).
C * Without the nc entry points, this becomes around 1800 bytes of object
C code; the nc code adds over 1000 bytes. We should perhaps sacrifice a
C few cycles for the non-nc code and let it fall into the nc code.
