43f88a22f0 Add a SymbolicFile interface between Binary and ObjectFile. 
This interface allows IRObjectFile to be implemented without having dummy
methods for all section and segment related methods.

Both llvm-ar and llvm-nm are changed to use it. Unfortunately the mangler is
still not plugged in since it requires some refactoring to make a Module hold
a DataLayout.

a11df1035e Make ObjectFile ownership of the MemoryBuffer optional. 
This allows llvm-ar to mmap the input files only once.

4157b2a6c1 Pass the computed magic to createBinary and createObjectFile if available. 
identify_magic is not free, so we should avoid calling it twice. The argument
also makes it cheap for createBinary to just forward to createObjectFile.

966babad9e Return an ErrorOr<Binary *> from createBinary. 
I did write a version returning ErrorOr<OwningPtr<Binary> >, but it is too
cumbersome to use without std::move. I will keep the patch locally and submit
when we switch to c++11.

c44b97c596 At Jim Grosbach's request detemplate Object/MachO.h. 
We are still able to handle mixed endian objects by swapping one struct at a
time.

2174f713f4 Remove unnecessary classof()'s 
isa<> et al. automatically infer when the cast is an upcast (including a
self-cast), so these are no longer necessary.
