This is very rough but allows one to do

> $ lldb
> (lldb) attach firefox
> Process 91725 stopped
> Executable module set to "/Applications/FirefoxNightly.app/Contents/MacOS/firefox".
> Architecture set to: x86_64-apple-macosx.
> (lldb) callfunc mozilla_sampler_save_profile_to_file("/Users/mstange/Desktop/profile.txt")

in order to get a profile from a hung Nightly.

Seems reasonable to me. Ehsan might want to take a look as he's reviewed things in this file before.

You should also probably do the responsible thing and file a bug against lldb that you can put in a comment for this helper giving the motivation.
