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

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

theoretical fix since it only matters for types with >= 2^63 bits (!) and also
only matters if pointers have more than 64 bits, which is not supported anyway.

For the time being, skip the relevant disassemble action which resulted in a crash.
Minor modification (print out format) to the existing TestDisassembleRawBytes.py test file.

-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.

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.

We cannot limit the concatenated instruction names to 64K. ARM is
already at 32K, and it is easy to imagine a target with more
instructions.

This patch limited the concatenated register names to 64K which meant
that the total number of registers was many times less than 64K.
If any compilers actually enforce the 64K limit on string literals, and
it turns out to be a problem, we should fix that problem by not using
long string literals.

Fixed a case where if you have a argument stirng that ends with a '\' character, it would infinite loop while consuming all of your memory.
Also fixed a case where non-quote terminated strings would inefficiently be handled.

Made sure that the root XPC service validate the right before starting the service. The right is created and authenticated by clients (in this case, lldb) and transferred over for validiation.
