Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide

Changes made by clang-tidy with minor tweaks.

Move the ARM EHABI unwind opcode definitions from the ARM MCTargetDesc into LLVM
Support. This enables sharing of the definitions across the ARM target code as
well as llvm-readobj. This will allow implementation of the unwind decoding in
llvm-readobj.
