I am surprised by this. In a quick experiment `flang-new -mmlir -mlir-pass-statistics -c [...]` gives me the same output both with and without `-fopenmp`. Why isn't `CodeGenRewrite` doing the job for you? This pass should run earlier than `FIRToLLVMLowering` (`CodeGen.cpp`).  

In @jeanPerier's commit adding `fir::DeclareOp` to `PreCGRewrite.cpp`, he mentions that it was placed here to avoid adding support for `fir.shape` to codegen.  See c852174a49
