The documentation of the checker:

/// The emptiness of a container should be checked using the empty method
/// instead of the size method. It is not guaranteed that size is a

/// empty method but not implement the size method. Using empty whenever
/// possible makes it easier to switch to another container in the future.

It also uses some custom ASTMatchers. In case you find them useful I can submit
them as separate patches to clang. I will apply your suggestions to this patch.

Modified LLDB to be able to lookup global variables by address.

The eSymbolContextEverything purposely does not include the new eSymbolContextVariable in its lookup since stack frame code does many lookups and we don't want it triggering the global variable lookups.
