Without SSE2 enabled, x86 targets will use x87 FPU, which breaks the tests checking for reproducible results from our random floating point number generators. The output is still reproducible, at least between binaries targetting x87, but the tests hardcode results for the whole pipeline being done in 32/64bit precision. Closes #2796
By moving to use our `uniform_integer_distribution`, which is reproducible across different platforms, instead of the stdlib one which is not, we can provide reproducible results for `float`s and `double`s. Still no reproducibility for `long double`s, because those are too different across different platforms.
* Utility for extended mult n x n bits -> 2n bits * Utility to adapt output from URBG to target (unsigned) integral type * Utility to reorder signed values into unsigned type while keeping the order.
Specifically we add * `gamma(a, b)`, which returns the magnitude of largest 1-ULP step in range [a, b]. * `count_equidistant_float(a, b, distance)`, which returns the number of equi-distant floats in range [a, b].
