The existing `mlir::populateMathPolynomialApproximationPatterns` is coarse-grained and inflexible: - It populates 2 distinct classes of patterns: (1) polynomial approximations, (2) expansions of operands to f32. - It does not offer knobs to select which math functions to apply the rewrites to. This PR adds finer-grained populate-patterns functions, which take a predicate lambda allowing the caller to control which math functions to apply rewrites to.
