When debugging LLDB itself, it can often be useful to know the mangled name of the function where a breakpoint is set. Since the `--verbose` setting of `break --list` is aimed at debugging LLDB, this patch makes it so that the mangled name is also printed in that mode. Note about testing: since mangling is not the same on Windows and Linux, the test refrains from hardcoding mangled names.
