Full time series profiling data

[Rik]

With Mike's patches I was able to compile historical versions of Octave all the way back to 3.2.X series.  Results are below.

Version	3.2.4	3.4.3	3.6.4	3.8.2	4.0.3	4.2.1	4.4.1	5.1.0	dev (6.0.0)
Benchmark
bm.toeplitz.orig.m	5.8968	4.4943	5.0851	5.5534	10.055	10.544	13.052	13.481	13.291

There were two step change losses.  The first between 3.8.X series and 4.0.X series.  The second between 4.2.X and 4.4.X series.
