performance: Fix signedness of ints throughout
The tests were using a lot of signed `int`s when actually the values
being handled were always non-negative. Use `unsigned int` consistently
throughout.

Take the opportunity to move declarations of loop iterator variables
into the loops.

This introduces no functional changes.
