a method implemented by the class then this load can safely be marked as an
inviarant because a message must have been passed to the class at some point,
forcing the ivar offset to be resolved.

An additional heuristic that can be used to identify an invariant load would be
if the ivar offset base is a parameter to an objc method.  However, without the

Fixed a crasher when the ConnectionFileDescriptor was used in a process with over FD_SETSIZE (1024) files open. It would corrupt the stack and cause the stack checker to assert and kill the program.

The final fix was to "#define _DARWIN_UNLIMITED_SELECT" at the top of the one and only file that uses select () in the LLDB codebase and then make an array of "fd_set" objects so they can handle more than 1024 file descriptors. The new code can handle as many file descriptors as a process can create.
