Fix ambiguity detection in GetBestOverloadCandidateSimple.

When performing the simplistic overload resolution for single-argument methods,
don't check the best overload for ambiguity with itself when the best overload
doesn't happen to be the first one.

Fixes PR13480.

Make -Wformat check the argument type for %n.

This makes Clang check that the corresponding argument for "%n" in a

[analyzer] Introduce a CallEventManager to keep a pool of CallEvents.

This allows us to get around the C++ "virtual constructor" problem
when we'd like to create a CallEvent from an ExplodedNode, an inlined
StackFrameContext, or another CallEvent. The solution has three parts:

- CallEventManager uses a BumpPtrAllocator to allocate CallEvent-sized
  memory blocks. It also keeps a cache of freed CallEvents for reuse.
- CallEvents all have protected copy constructors, along with cloneTo()
  methods that use placement new to copy into CallEventManager-managed
  memory, vtables intact.
- CallEvents owned by CallEventManager are now wrapped in an
  IntrusiveRefCntPtr. Going forwards, it's probably a good idea to create
  ALL CallEvents through the CallEventManager, so that we don't accidentally
  try to reclaim a stack-allocated CallEvent.

All of this machinery is currently unused but will be put into use shortly.

Do not warn on correct use of the '%n' format specifier.

While '%n' can be used for evil in an attacker-controlled format string, there
isn't any acute danger in using it in a literal format string with an argument
of the appropriate type.

[analyzer] Only allow CallEvents to be created by CallEventManager.

This ensures that it is valid to reference-count any CallEvents, and we
won't accidentally try to reclaim a CallEvent that lives on the stack.
It also hides an ugly switch statement for handling CallExprs!

There should be no functionality change here.
