Emit warning when operand to `delete` is allocated with `new[]` or
operand to `delete[]` is allocated with `new`.
rev 2 update:
`getNewExprFromInitListOrExpr` should return `dyn_cast_or_null`
instead of `dyn_cast`, since `E` might be null.

This reverts commit 742dc9b6c9686ab52860b7da39c3a126d8a97fbc.
This is generating multiple segfaults in our internal builds.
Test case coming up shortly.

Some checkers ascribe different behavior to functions declared in system
headers, so when working with standard library functions it's probably best
to always have them in a standard location.
Test change only (no functionality change), but necessary for the next commit.

report mismatched deallocator
Test that the path notes do not change. I don’t think we should print a note on escape.
Also, I’ve removed a check that assumed that the family stored in the RefStete could be
AF_None and added an assert in the constructor.

As mentioned in the previous commit message, the use-after-free and
double-free warnings for 'delete' are worth enabling even while the
leak warnings still have false positives.

This splits the leak-checking part of alpha.cplusplus.NewDelete into a
separate user-level checker, alpha.cplusplus.NewDeleteLeaks. All the
difficult false positives we've seen with the new/delete checker have been
spurious leak warnings; the use-after-free warnings and mismatched
deallocator warnings, while rare, have always been valid.

MallocChecker.cpp
This fixes an issue pointed to by Jordan: if unix.Malloc and unix.MismatchedDeallocator are both on, then we end up still tracking leaks of memory allocated by new.
Moved the guards right before emitting the bug reports to unify and simplify the logic of handling of multiple checkers. Now all the checkers perform their checks regardless of if they were enabled, or not, and it is decided just before the emitting of the report, if it should be emitted. (idea from Anna).
Additional changes:
improved test coverage for checker correlations;
refactoring: BadDealloc -> MismatchedDealloc
