b5c9ee756f Make test_point_times_order test meaningful again 
As wnaf splitting is scalar based, multiplying with the order directly
would be reduced to multiplication with zero before even converting to
wnaf.

5dd421bab5 Rewrite mul/sqr for 32bit/64bit 
- interleave calculation of the lower and upper partial product ranges, and reduction
- less registers needed, more opportunities for parallel ops

Wno-unused-function is used for the moment because of the checking
 functions which are currently only used by VERIFY but are not (yet?)
 ifdefed out in normal builds.
