C++: Tie macro exclusion to <, not +
...
This fixes a failing qltest and makes the exclusion similar to what's in
`PointerOverflow.ql`. It's possible we should exclude based on both `+`
and `<`, but we can revisit that if false positives show up.

C++: Prevent cached stages from being re-evaluated
...
Before this change, evaluating `cpp/constant-comparison` followed by
`cpp/signed-overflow-check` would result in re-evaluation of almost all
the cached stages they share: CFG, basic blocks, SSA, and range
analysis. The same effect could be seen on `cpp/bad-strncpy-size`, which
also uses the GVN library.

C++/C#: Fix compilation error in PrintSSA.qll
...
We were privately importing `semmle.code.<lang>.ir.internal.Overlap`, but `PrintSSA.qll` was depending on it being public. This is made a little more complicated by the presence of cross-langage pyrameterized modules.

C++: Use isFromMacroDefinition for exclusion
...
The `SignedOverflowCheck.ql` query was very slow on certain snapshots
(jluttine/suitesparse and Chromium) due to bad magic in
`MacroInvocation::getAnAffectedElement_dispred#fb`. This commit doesn't
fix the bad magic but changes the exclusion mechanism to use a predicate
where we can better control the magic and optimization.
The query should also give more good results due to this new exclusion
mechanism, which is the same one used in its sibling,
`PointerOverflow.ql`.
