[llvm] r272721 - [PM] Port WholeProgramDevirt to the new pass manager.

[Davide Italiano via llvm-commits]

The run() method here was already incapsulated inside another object,
so I avoided too much code churn and not renamed WholeProgramDevirt ->
WholeProgramDevirtLegacy. If you want me to do that, just let me know.

Thanks,
