math.log() benchmark of first 1 billion int using std.parallelism

[Iov Gherman via Digitalmars-d-learn]

So, I did some more testing with the one processing in paralel:

--- dmd:
4 secs, 977 ms

--- dmd with flags: -O -release -inline -noboundscheck:
4 secs, 635 ms

--- ldc:
6 secs, 271 ms

--- gdc:
10 secs, 439 ms

I also pushed the new bash scripts to the git repository.
