b8a5aa5d85 C++: Fix a couple of range analysis issues: 
1. The new query is expecting pointer arithmetic operations to generate
range-analysis bounds, but this wasn't true on main.
2. The bounds generated by `boundFlowCond` was incorrectly inferred as
non-strict when comparing a pointers (unlike when comparing values of
integral types). This gave FPs in the new query.

This also fixes a couple of missing results in existing queries that
use the new range-analysis library.
