Summary: This implements searching for function symbols and public symbols by address. More specifically, -Implements NativeSession::findSymbolByAddress for function symbols and public symbols. I think data symbols are also searched for, but isn't implemented in this patch. -Adds classes for NativeFunctionSymbol and NativePublicSymbol -Adds a '-use-native-pdb-reader' option to llvm-symbolizer, for testing purposes.
