Give some convenient idiomatic accessors to Stmt::child_range and
...
Stmt::const_child_range, then make a bunch of places use them instead
of the individual iterator accessors.

Don't emit a dead store for '++' operations unless it occurs with a return statement. We've never seen any other cases that were real bugs.

Fix bug in ParentMap::isConsumedExpr. A BinaryOperator always "consumes" the
...
value of its subexpressions unless it is a comma (in which case it doesn't
consume the left subexpression).

Fix: <rdar://problem/6740387>. Sending nil to an object that returns a struct
...
should only be an error if that value is consumed. This fix was largely
accomplished by moving 'isConsumedExpr' back to ParentMap.

Dead stores checker: Fix <rdar://problem/6506065> by being more selective when say that a store is dead even though the computed value is used in the enclosing expression.

More #include cleaning
...
- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.
