This new name is similar to its sister query "Signed overflow check".

1b849dbf0e C++: More principled macro exclusion 
We no longer exclude macros based on their name, which means we can now
find results inside arguments to the `likely` macro in Linux (except
that Linux is compiled with `-fno-strict-overflow`).

8d79634f8c C++: Factor out isFromMacroDefinition predicate 
This trick for excluding elements from macro bodies but not macro
arguments looks promising and should probably be used much more. With
this commit, it's now easy to use from any query.

Performance is still good because the new predicate gets appropriately
magiced.

8ed991759c C++: Rename PointerWrapAround to PointerOverflow 
Overflow was the terminology I found for this in the C standard (C11
