Before the print function was just implicitly called somewhere

LeastSquaresSolver: Fix nasty GCC compile optimization error
...
The original implementation with no wrapping on size_t is more readable
but the compiler errors with:
internal compiler error: in trunc_int_for_mode, at explow.c:55
I read up and it's apparently a loop optimization problem.
Inspired by https://stackoverflow.com/a/27224697/6326048
I used a far less readable implementation that works fine and
wrote a comment to explain it.

Matrix: remove unsafe copyToRaw method
...
It used a pointer and could therefore not do correct type checking
for index out of bound or struct memebr order.
Has to be considered unsafe and bad practise.
We should switch to arrays as representation for vectors
inside the messages instead of foo_x, foo_y, foo_z fields.
