Added new -lower-math-early option that defaults to 'true' that matches the current math lowering scheme. If set to 'false', the intrinsic math operations will be lowered to MLIR operations, which should potentially enable more MLIR optimizations, or libm calls, if there is no corresponding MLIR operation exists or if "precise" mode is requested. The generated math MLIR operations are then converted to LLVM dialect during codegen phase. The -lower-math-early option is not exposed to users currently. I plan to get rid of the "early" lowering completely, when "late" lowering is robust enough to support all math intrinsics that are currently supported via pgmath. So "late" mode will become default and -lower-math-early option will not be needed. This will effectively eliminate the mandatory dependency on pgmath in Fortran lowering, but this is WIP.
