[PATCH] D14965: [llc/opt] Add an option to run all passes twice

[Keno Fischer via llvm-commits]

I think what happens currently is that it will just append the second one
at the end of the first. I originally thought binary comparing the output
was not sensible as we're actually running over the same module twice and
the passes are of course not idempotent, but now I'm thinking maybe it's
better to clone the module and allow this. I'll take a look.
