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.

75873bb4a6 C++: Detect non-allocating placement new 
This adds a `NewOrNewArrayExpr.getPlacementPointer` predicate and uses
it in `Alloc.qll` to detect when a `new`-expression is not an
allocation.

User-defined replacements for `operator new` may not be allocations
either, but the code continues to assume that they are. It's possible
that we want to change this assumption in the future or leave it up to
individual queries to decide on which side to err. It's hard to
statically tell whether `operator new` has been overloaded in a
particular file because it can be overloaded by a definition that is not
in scope but is only linked together with that file.
