bug #1004 : one more rewrite of LinSpaced for floating point numbers to guarantee both interpolation and monotonicity.
...
This version simply does low+i*step plus a branch to return high if i==size-1.
Vectorization is accomplished with a branch and the help of pinsertlast.
Some quick benchmark revealed that the overhead is really marginal, even when filling small vectors.
