[PATCH] Disable passes on optnone functions

[Sean Silva]

  Is there an email thread that decided on this direction? (so that I can catch up) It seems really odd (and difficult to maintain) to litter the codebase with checks in each pass.

  In particular, what ever happened to just splitting all the notionally "optnone" functions into a separate module, and linking them back in at the end? That seems much more general. I don't see a response to <http://article.gmane.org/gmane.comp.compilers.llvm.cvs/160085> or a response to Nick's original suggestion (which was restricted to using the commandline tools). It seems very simple to split the module like that.
