552842346c C++: Fix special-casing of Qt library 
The `Expr.getType` predicate returns a pointer type since that's the
type of the `new`-expression as a whole. To find the class type, we use
`NewExpr.getAllocatedType`.

This commit reduces the number of alerts in a Qt snapshot from 229 to
51, and it removes the two false positives in
https://github.com/Subsurface-divelog/subsurface.

Conflict in `cpp/ql/test/library-tests/sideEffects/functions/sideEffects.expected`,
resolved by accepting test output (combining changes).

6239455a91 C++: Remove extra type check in AV Rule 82 
These type checks were overlapping with `assignOperatorWithWrongType` is
are no longer needed now that `assignOperatorWithWrongType` is improved.
They were causing FPs and misleading error messages on uninstantiated
templates.

8ac427c387 C++: Add missing getUnspecifiedType in AV Rule 82 
Adding this call to `getUnspecifiedType` makes the error message better
in the presence of typedefs and qualifiers on an assignment operator
return type. It's also needed to avoid losing valid results in the
commit that comes after this.

9382c9d528 C++: Regression tests for AV Rule 82 
Without the last commit, this addition to the test gives the following
results:

```
+| AV Rule 82.cpp:176:14:176:22 | operator= | Assignment operator in class Forgivable does not return a reference to *this. |
+| AV Rule 82.cpp:181:14:181:22 | operator= | Assignment operator in class Forgivable does not return a reference to *this. |

eef8719a40 C++: Fix AV Rule 85 
We have to be careful to avoid giving alerts to functions that might be
correctly defined, but we can't see the definition as it wasn't
instantiated.
