[Sema] Introduce a data recursive evaluator specific to binary operators.

This allows us to handle extreme cases of chained binary operators without causing stack
overflow.
The binary operators that are handled with the data recursive evaluator are
comma, logical, or operators that have operands with integral or enumeration type.

Part of rdar://10941790.

Make RecursiveASTVisitor to traverse certain statements using data recursion
to avoid a stack overflow with extreme cases.

[libclang] A couple of enhancements to c-index-test.

-When printing location avoid printing the filename if it is
same as the main file, not just if it has '.h' extension.
-Make sure we allocate enough bytes for storing as string a
huge line number.

[analyzer] Allow checkers to supply call stack diagnostic hints for the
BugVisitor DiagnosticPieces.

When checkers create a DiagnosticPieceEvent, they can supply an extra
string, which will be concatenated with the call exit message for every
call on the stack between the diagnostic event and the final bug report.
(This is a simple version, which could be/will be further enhanced.)

For example, this is used in Malloc checker to produce the ",
which allocated memory" in the following example:

static char *malloc_wrapper() { // 2. Entered call from 'use'
    return malloc(12);    // 3. Memory is allocated
}

void use() {
    char *v;
    v = malloc_wrapper(); // 1. Calling 'malloc_wrappers'
        // 4. Returning from 'malloc_wrapper', which allocated memory
}                         // 5. Memory is never released; potential
memory leak

It was pointed out that a checking version of strdup isn't needed. So much for late-night hacking. :)

[analyzer] Remove AggExprVisitor, a dead class that assisted in visiting C++ expressions with a "base object", because the CFG is now linearized.

The only use of AggExprVisitor was in #if 0 code (the analyzer's incomplete C++ support), so there is no actual behavioral change anyway.
