There is no good way to do that. As a partial workaround, you might
try calling getloclist(0), it should return [] if the current buffer is
a quickfix list, and something non-empty if it's a loclist. But this
may or may not work from an autocmd. Also, the filetype of the quickfix
buffer may be empty at that point if the quickfix has just been created.

Not really. Working with loclists is one of the darker corners of
Vim, using them for anything else than the built-in make, grep, and
friends is a huge pain.

That's even less reliable: if you create loclists with setloclist()
w:quickfix_title can be empty, or ':setloclist()', or something entirely
different.
