New description:
We implement functions that allow fast evaluations of integer polynomials
with real input:
- `fmpz_poly_evaluation_mpfr(mpfr_t res, const fmpz_poly_t poly, const
mpfr_t a)`
- `fmpz_poly_evaluation_mpfi(mpfi_t res, const fmpz_poly_t poly, const
mpfi_t a)`
- `ZZX_evaluation_mpfr(mpfr_t res, ZZX_c poly, const mpfr_t a)`
- `ZZX_evaluation_mpfi(mpfi_t res, ZZX_c poly, const mpfi_t a)`
These functions are integrated in the polynomial code with method
`_eval_mpfr` and `_eval_mpfi`.
