Remove beta_ij matrix and use a uniform weight for computing bounds relaxations.

@kronbichler ping I you have a minute, would you mind to instrument this pull request and compare it to the base branch? I do see a 2.5% performance improvement with clang on my laptop. (Which might be explained with less cache pressure in the already overburdened "step 4" of the hyperbolic update.) I am asking because 2.5% is huge. And now I dropped back to standard performance.

I will check this nonetheless. Not sure if I manage today, but I try to be quick.
