Summary:
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));
}
};
}
```
