the breakpoint associated with the (filename, line_number) combo when an arrow is pointing to a source position using Emacs Grand Unified Debugger library to interact with lldb. The current implmentation is insufficient in that it only asks the breakpoint whether it is associated with a breakpoint resolver with FileLine type and whether it matches the (filename, line_number) combo. There are other breakpoint resolver types whose breakpoint locations can potentially match the (filename, line_number) combo. The BreakpointResolver, BreakpointResolverName, BreakpointResolverAddress, and BreakpointResolverFileLine classes have extra static classof methods to support LLVM style type inquiry through isa, cast, and dyn_cast. The Breakpoint class has an API method bool GetMatchingFileLine(...) which is invoked from CommandObjectBreak.cpp to implement the "breakpoint clear" command. llvm-svn: 117562
