C++: Always normalize bounds after a computation
...
This stops some cases of `-0.0` from propagating through the range
analysis, fixing a false positive on arvidn/libtorrent.
There seems to be no need for a corresponding change in the caller of
`getDefLowerBoundsImpl` since that predicate only contains computations
that cannot introduce negative zero.
