This can't be in python - the main LLDB code needs to support it.
* LLVM supports it using a preprocessor define, which obviously won't work because
it is compiled in. LLVM will have to be made to check flags at runtime.
* LLDB can be fixed to support both via it's PathSyntax functionality, but
the question is how to do this cleanly. I proposed adding an option.

Yeah, that was the gdb way of supporting alternate functionality
(to check if a function was defined and call it) - it worked pretty
well. It doesn't really fit in well with LLDB design however. LLDB's
way of supporting alternate functionalities is through plugins or
options. In this case an option seems most reasonable.
