fabs -> fabsl
...
Fixes two calls that were using `fabs` on a `long double` argument rather than `fabsl`, which looks like it is doing an unintentional truncation to `double` precision.

Fixed a few more unnecessary calls to num_cpu_avail.
...
I don't have as many benchmarks for these as for gemm, but it should still
make a difference for small matrices.

Improve performance of GEMM for small matrices when SMP is defined.
...
Always checking num_cpu_avail() regardless of whether threading will actually
be used adds noticeable overhead for small matrices. Most other uses of
num_cpu_avail() do so only if threading will be used, so do the same here.

Keep the flag handling separate from the scaling loops
...
Fixes #1452 and is more in line with how ATLAS does it. The earlier fix from #356 only moved the bug elsewhere, but we will never want the iterative rescaling to change the dflag setting and variable associations with each cycle.
