Harlan Haskins 84586c1423 [clang] Change FileManager to use llvm::ErrorOr instead of null on failure ...

Summary:
Currently, clang's FileManager uses NULL as an indicator that a particular file
did not exist, but would not propagate errors like permission issues. Instead,
teach FileManager to use llvm::ErrorOr internally and return rich errors for
failures.
