StaticAnalyzer: Move ObjC- and CXX-specific methods out of line so checkers that don't care about the language don't have to pull in all the headers.

At this point this is largely cosmetic, but it opens the door to replace
ProgramStateRef with a smart pointer that more eagerly acts in the role
of reclaiming unused ProgramState objects.

Specifically, CFArrayCreate's input should be:
'A C array of the pointer-sized values to be in the new array.'

Rework flushing of diagnostics to PathDiagnosticConsumer.  Now all the reports are batched up before being flushed
to the underlying consumer implementation.  This allows us to unique reports across analyses to multiple functions (which
shows up with inlining).

This is accomplished by periodically reclaiming nodes in the graph.  This was an optimization
done before the CFG was linearized, but the CFG linearization destroyed that optimization since each
freshly created node couldn't be reclaimed and we only looked at a window of nodes created between
each ProcessStmt.  This optimization can be reclaimed my merely expanding the window to N number of nodes.

[analyzer] It's possible to have a non PointerType expression evaluate to a Loc value. When this happens, use the default type.

Also, slightly modify the diagnostic message in ArrayBound and DivZero (still use 'taint', which might not mean much to the user, but plan on changing it later).

Reenable DeadStoresChecker under --analyze, and move the IdempotentOperationsChecker to the 'experimental' category.  Fixes <rdar://problem/10146347>.

This could be useful when checkers' logic depends on whether a function

(Maybe some of this could migrate to the CString checker. One issue
with that is that we might want to separate security issues from
regular API misuse.)

- Add atomic-to/from-nonatomic cast types
- Emit atomic operations for arithmetic on atomic types
- Emit non-atomic stores for initialisation of atomic types, but atomic stores and loads for every other store / load
- Add a __atomic_init() intrinsic which does a non-atomic store to an _Atomic() type.  This is needed for the corresponding C11 stdatomic.h function.
- Enables the relevant __has_feature() checks.  The feature isn't 100% complete yet, but it's done enough that we want people testing it.

Still to do:

- Make the arithmetic operations on atomic types (e.g. Atomic(int) foo = 1; foo++;) use the correct LLVM intrinsic if one exists, not a loop with a cmpxchg.
- Add a signal fence builtin
- Properly set the fenv state in atomic operations on floating point values
- Correctly handle things like _Atomic(_Complex double) which are too large for an atomic cmpxchg on some platforms (this requires working out what 'correctly' means in this context)
- Fix the many remaining corner cases
