  Log Message:
  -----------
  [flang][OpenMP] Tolerate compiler directives in loop constructs

PR168884 flagged compiler directives (!dir$ ...) inside OpenMP loop
constructs as errors. This caused some customer applications to fail
to compile (issue 169229).

Downgrade the error to a warning, and gracefully ignore compiler
directives when lowering loop constructs to MLIR.

Fixes https://github.com/llvm/llvm-project/issues/169229
