We have a list of "Supported Languages" (Language::GetSupportedLangauges) which
are the ones we actually have plugins for as opposed to the ones whose names we
know. That's the list you should be querying.
We should add a new API to the Language plugin:
Language::GetUserEntrypointName() and then this code should iterate over all
the supported languages building up a unique list of entry point names using
this API. At present there's going to be one: "main" repeated many times but I
think Walter promised us another one soon...
If you find more than one name, there's a Target::CreateBreakpoint overload
that takes a `const char *func_names[]` - that you can use to make one
portmanteau breakpoint for all the entry point names.
It's also a good idea to add a shared library filter instead of the first
`nullptr` in the code above, and specify the main executable. You know the
entry point has to be in the main executable, and so it would be inefficient to
search the whole world for this breakpoint. It could also end up not being
what you want, because some other shared library might call a function named
"main" as part of it's shared library loading code (which happens before the
language's entry point) so you would in fact stop too early.
You'll need to pass eLanguageTypeUnknown for the language.
