1cc36dd969 C++: Exclude copy assignment in LargeParameter.ql
The purpose of the copy assignment operator is to copy the object, so we
should not complain that a copy happens when passing the parameter. See
https://en.wikibooks.org/wiki/More_C++_Idioms/Copy-and-swap for details.

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.
