[PATCH] Add a callback to FunctionPass to enable skipping execution on a per-function basis

[Eric Christopher]

Hi Akira,

Yep. This is about what I was thinking about when we chatted. It seems to be a bit less cognitive overhead than a pass decorator, which would just be another (possible TargetMachine local) pass framework that implements Pass with a pile of overloads.

What do you think Chandler?
