Yes, for the ones that have the C snippet, I re-created from that. Since the IR is quite different now, I thought this was the best way and less error-prone while generating the new IR.

Can you help update these tests by getting the patch locally?

These have the C snippet.

LLVM :: Transforms/OpenMP/custom_state_machines.ll
LLVM :: Transforms/OpenMP/custom_state_machines_remarks.ll
LLVM :: Transforms/OpenMP/gpu_state_machine_function_ptr_replacement.ll
LLVM :: Transforms/OpenMP/spmdization.ll
LLVM :: Transforms/OpenMP/spmdization_assumes.ll
LLVM :: Transforms/OpenMP/spmdization_guarding.ll
LLVM :: Transforms/OpenMP/spmdization_guarding_two_reaching_kernels.ll
LLVM :: Transforms/OpenMP/spmdization_remarks.ll

I think the following are updated correctly and pass.

LLVM :: Transforms/OpenMP/get_hardware_num_threads_in_block_fold.ll
LLVM :: Transforms/OpenMP/is_spmd_exec_mode_fold.ll
LLVM :: Transforms/OpenMP/parallel_level_fold.ll

I was not able to update the following, so it fails.

LLVM :: Transforms/OpenMP/spmdization_constant_prop.ll
