Reimplemented mpfr_set_si_2exp and mpfr_set_ui_2exp, and mpfr_set_si
and mpfr_set_ui using the 2exp versions with e = 0. This fixes a bug
in corner cases (emin >= 4 and some other constraints) in mpfr_set_si
and mpfr_set_ui that incorrectly lead to an underflow flag set, and
fixes mpfr_set_si_2exp and mpfr_set_ui_2exp in case of overflow or
underflow (replacing the r4346 fix). Added corresponding testcases.
