The previous value of epsilon, which was pulled form the qmckl_context
and reused fot the qmckl probes, was arout 4.10^-16. It's a good value
to use for the tests with IEEE arithmetic, however, MCA introduces some
noise which is at this order of magnitude, and caused one probe in
particular to fail, while its accuracy was actually satisfying.
This value is now multiplied by 16 if VFC_CI is defined (to ask for 4
less significant digits in base 2), which makes more sense for MCA.
Some checks in the AO test were not correctly ignored by the
preprocessor when vfc_ci support was enabled. This caused the test to
fail unexpectedly and made it impossible to get data from it in vfc_ci.
Some asserts where not correctly ignored with vfc_ci and caused tests to
exit prematurely when compiling the library with Verificarlo and using
stochastic backends.
The target has been set to 1d.-14 (or epsilon), because this was the value already
used in the tests. However this might not be the best choice with the
non-deterministic backend, so it might be necessary to adjust it in the
future.
Also, the expectedValue argument has been set to 0 since it is not used.
(the tests checks have already been written anyway)
Since we don't need to place probs on all matrices, a simple solution
seems to monitor one element of the matrix. A solution could be to
compute a matrix norm / residual but this would make the tests more
complex.
