llvm-nm only needs the target to parse module level assembly in bitcode. It doesn't need a disassembler or codegen.
llvm-objdump needs to be able to disassemble a file, but doesn't need asm parsers or codegen.
This reduces the sizes of these tools by a few MB each, depending on how many backends are linked in.

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.
