[PATCH] D51089: [LLD] [COFF] [RFC] Add support for creating range extension thunks for ARM

Updated taking @ruiu and @peter.smith's feedback into account. I still haven't added more tests though, so that's still a clear todo, but reposting for more potential feedback meanwhile.

I updated the code to keep the thunk maps between passes, which leads to much fewer additions in later passes (originally I could occasionally hit up to 8 passes before things were done, now it gets done in 3 passes), and fixed code to avoid chaining thunks in case the originally chosen thunk went out of range.
