There exist [Arm extensions for ELF](https://developer.arm.com/documentation/ihi0044/h/?lang=en). This PR aims to add support to `goblin`. `goblin::elf::arm` defines some contents and some extension traits which add Arm-specific functionality to existing `goblin` types....

LLVM recently added PDB output support, and [some of their tests](https://github.com/llvm-mirror/llvm/tree/57f9d8ea2f0641a9da605d60e0653e1081e87d2a/test/DebugInfo/PDB) seem like they would be useful to port. - [ ] [`every-type.test`](https://github.com/llvm-mirror/llvm/blob/57f9d8ea2f0641a9da605d60e0653e1081e87d2a/test/DebugInfo/PDB/every-type.test) / [`yaml`](https://github.com/llvm-mirror/llvm/blob/57f9d8ea2f0641a9da605d60e0653e1081e87d2a/test/DebugInfo/PDB/Inputs/every-type.yaml) / [`cpp`](https://github.com/llvm-mirror/llvm/blob/57f9d8ea2f0641a9da605d60e0653e1081e87d2a/test/DebugInfo/PDB/Inputs/every-type.cpp) / [`pdb`](https://github.com/llvm-mirror/llvm/blob/57f9d8ea2f0641a9da605d60e0653e1081e87d2a/test/DebugInfo/PDB/Inputs/every-type.pdb) -...
