5ee19c5a66 C++: Stricter loop-variant check 
The `loopVariant` predicate in `ComparisonWithWiderType.ql` is intended
to identify loop counters, but it was too much of a stretch to apply it
to any subexpression of the small side of the comparison.

This change fixes two false positives on arvidn/libtorrent and many
others seen in the wild (on Linux, CoreCLR, ffmpeg, ...).

bd4fa10ffb 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.

0e4ed1cbbf 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.

27cc6b1e4f 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.

7f26f078eb C++: Fix isFromMacroDefinition join order

82499b035b 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`.
