[PATCH] D71086: Let PassBuilder Expose PassInstrumentationCallbacks

[Juneyoung Lee via Phabricator via llvm-commits]

This is an effort to allowing external libraries register their own pass instrumentation during their llvmGetPassPluginInfo() calls.

By exposing this through the added getPIC(), now a pass writer can do something like this:

  extern "C" ::llvm::PassPluginLibraryInfo LLVM_ATTRIBUTE_WEAK
  llvmGetPassPluginInfo() {
    return {
      ..,
      [](llvm::PassBuilder &PB) {
        PB.getPIC()->registerAfterPassCallback(move(f));
      }
    };
  }
