[analyzer][NFCI] Allow clients of NoStateChangeFuncVisitor to check entire function calls, rather than each ExplodedNode in it
D105553 added NoStateChangeFuncVisitor, an abstract class to aid in creating
notes such as "Returning without writing to 'x'", or "Returning without changing
the ownership status of allocated memory". Its clients need to define, among
other things, what a change of state is.
For code like this:
f() {
g();
}
foo() {
f();
h();
}
We'd have a path in the ExplodedGraph that looks like this:
-- <g> -->
/ \
--- <f> --------> --- <h> --->
/ \ / \
-------- <foo> ------ <foo> -->
When we're interested in whether f neglected to change some property,
NoStateChangeFuncVisitor asks these questions:
÷×~
-- <g> -->
ß / \$ @&#*
--- <f> --------> --- <h> --->
/ \ / \
-------- <foo> ------ <foo> -->
Has anything changed in between # and *?
Has anything changed in between & and *?
Has anything changed in between @ and *?
...
Has anything changed in between $ and *?
Has anything changed in between × and ~?
Has anything changed in between ÷ and ~?
...
Has anything changed in between ß and *?
...
This is a rather thorough line of questioning, which is why in D105819, I was
only interested in whether state *right before* and *right after* a function
call changed, and early returned to the CallEnter location:
if (!CurrN->getLocationAs<CallEnter>())
return;
Except that I made a typo, and forgot to negate the condition. So, in this
patch, I'm fixing that, and under the same hood allow all clients to decide to
do this whole-function check instead of the thorough one.

[analyzer][NFC] Introduce CXXDeallocatorCall, deploy it in MallocChecker
One of the pain points in simplifying MallocCheckers interface by gradually
changing to CallEvent is that a variety of C++ allocation and deallocation
functionalities are modeled through preStmt<...> where CallEvent is unavailable,
and a single one of these callbacks can prevent a mass parameter change.
This patch introduces a new CallEvent, CXXDeallocatorCall, which happens after
preStmt<CXXDeleteExpr>, and can completely replace that callback as
demonstrated.
