Michael Zolotukhin bcf5523bc8 [GlobalDCE] Use DenseMap instead of unordered_multimap for GVDependencies. ...

Summary:
std::unordered_multimap happens to be very slow when the number of elements
grows large. On one of our internal applications we observed a 17x compile time
improvement from changing it to DenseMap.
