Daniel R. Carvalho 8ba0ba4871 base: Fix negative op-assign of SatCounter ...

The value of the add and subtract assignment operations can be negative,
and this was not being handled properly previously. Regarding shift
assignment, the standard says it is undefined behaviour if a negative
number is given, so add assertions for these cases.
