833fea40 - [MLIR][OpenMP] Add `private` clause to `omp.parallel` (#81452)

[MLIR][OpenMP] Add `private` clause to `omp.parallel` (#81452) Extends the `omp.parallel` op by adding a `private` clause to model [first]private variables. This uses the `omp.private` op to map privatized variables to their corresponding privatizers. Example `omp.private` op with `private` variable: ``` omp.parallel private(@x.privatizer %arg0 -> %arg1 : !llvm.ptr) { ^bb0(%arg1: !llvm.ptr): // ... use %arg1 ... omp.terminator } ``` Whether the variable is private or firstprivate is determined by the attributes of the corresponding `omp.private` op.
