[llvm-branch-commits] [mlir] [MLIR][OpenMP] NFC: Remove LoopControl parsing/printing code (PR #88909)

[Sergio Afonso via llvm-branch-commits]

https://github.com/skatrak created https://github.com/llvm/llvm-project/pull/88909

This patch removes the LoopControl parsing/printing functions that are no longer used after transitioning `omp.simdloop` and `omp.taskloop` into loop wrapper operations.

Subject: [PATCH] [MLIR][OpenMP] NFC: Remove LoopControl parsing/printing code

longer used after transitioning `omp.simdloop` and `omp.taskloop` into loop
wrapper operations.
