This implements an LLVM tool that's flag- and output-compatible with macOS's `otool` -- except for bugs, but from testing with both `otool` and `xcrun otool-classic`, llvm-otool matches vanilla otool's behavior very well already. It's not 100% perfect, but it's a very solid start. This uses the same approach as llvm-objcopy: llvm-objdump uses a different OptTable when it's invoked as llvm-otool. This is possible thanks to D100433. Differential Revision: https://reviews.llvm.org/D100583
