Flow-sensitive uninitialized values analysis: properly handle the 'element' expression of ObjCForCollectionStmt (can be anything).

function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

Don't require us to manually number the statements and expressions in StmtNodes.def. We don't need stable numbers yet, renumbering is a pain, and LAST_STMT had the wrong value anyway.

Fix an obscure rewriter bug when rewriting implementations that don't have a corresponding interface (found while doing random testing on another bug).

1. In the top level of ParseStatementOrDeclaration, don't eat a } if we
   just parsed a statement if it list there.  Also, don't even bother
   emitting an error about a missing semicolon if the statement had a 
   bug (an rbrace is fine).
2. In do/while parsing, don't require a 'while' to be present if the do
   body didn't parse.

This allows us to generate a clean diagnostic for this code:

t.c:1:22: error: expected expression
void foo (void) { do . while (0); }
                     ^

Thanks to Neil for pointing this out.

Using llvm::OwningPtr<> for CurLexer and CurTokenLexer.  This makes both the ownership semantics of these objects explicit within the Preprocessor and also tightens up the code (explicit deletes not needed).

Use PushIncludeMacroStack/PopMacroStack instead of manually pushing/popping from IncludeMacroStack.  This is both cleaner and makes the include stack transparently extensible.

some more bullet-proofing/enhancements for tryEvaluate.  This shouldn't 
cause any behavior changes except for handling cases where we were 
crashing before and being able to evaluate a few more cases in tryEvaluate.
 
This should settle the minor mess surrounding r59196.
