actually, this is not even meant to be a termination criterion. so the proper fix is this.

* fix bug thanks to Ben Goodrich: we were terminating at the wrong place, leaving some matrix coefficients with wrong values.
* don't use Higham's formula here: we're not trying to be rank-revealing.

Further LU test improvements. I'm not aware of any test failures anymore, not even with huge numbers of repetitions.
...
Finally the createRandomMatrixOfRank() function is renamed to createRandomPIMatrixOfRank, where PI stands for 'partial isometry', that is, a matrix whose singular values are 0 or 1.

* FullPivLU: replace "remaining==0" termination condition (from Golub) by a fuzzy compare
...
(fixes lu test failures when testing solve())
* LU test: set appropriate threshold and limit the number of times that a specially tricky test
is run. (fixes lu test failures when testing rank()).
* Tests: rename createRandomMatrixOfRank to createRandomProjectionOfRank

if a and/or b as to be evaluated. So in the next commit I'll remove it. A nice
solution would be to evaluate the lhs/rhs into member of the initial product,
