A few OpenMP tests were retaining the FIR operands even after running the LLVM conversion pass. To fix these tests the legality checkes for OpenMP conversion are made stricter to include operands and results. The Flush, Single and Sections operations are added to conversions or legality checks. The RegionLessOpConversion is appropriately renamed to clarify that it works only for operations with Variable operands. The operands of the flush operation are changed to match those of Variable Operands. Fix for an OpenMP issue mentioned in https://github.com/llvm/llvm-project/issues/55210.
