C++: Support overriding existing range bounds
...
The current support only allows the user to supply bounds for previously
unsupported expressions or for variable accesses. This commit allows
SimpleRangeAnalysisExprs to override built-in range definitions.

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.
