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.

Add slicing tests that are not pure row slicing
...
I had a look at the implementation of `slice`, and I found it odd that it doesn't have a copy loop. The current implementation does a raw memcpy of the underlying contiguous row-major data. As far as I can tell, this could only slice along rows. Interestingly, I found that the tests only tested for slicing along rows, so this bug would go unnoticed.
I added some tests that checks slicing along columns also. I have a feeling this would break, and we need to fix the implementation of `slice`. However I could be wrong, and hence I'm submitting these tests first to verify.

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.
