  [LLVM][TableGen] Fix Windows failure in DecoderEmitter (#136310)

- Avoid dereferencing the end() iterator to get the end pointer, instead
calculate it explicitly
- Fixes a regression introduced in
https://github.com/llvm/llvm-project/pull/136220.
- The windows build failure shows the following call stack:
