  -----------
  [MLIR][GPU] Disallow llvm tanh intrinsics when lowering to NVVM/ROCm.

Summary:
The lowering to NVVM and ROCm handles tanh operations differently by
mapping them to NVVM/ROCm specific intrinsics. This conflicts with
the lowering to LLVM, which uses the default llvm intrinsic. This change
declares the LLVM intrinsics to be illegal, hence disallowing the
correspondign rewrite.
