PR13433: In Microsoft mode, don't require function calls within decltype
expressions to have complete return types (or accessible destructors). If the
return type is required to be complete for some other reason (for instance, if
it is needed by overload resolution), then it will still be required to be
complete. This is apparently required in order to parse a MSVC11 header.

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.

[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.
