defaults.h (LARGEST_EXPONENT_IS_NORMAL, [...]): New.
* defaults.h (LARGEST_EXPONENT_IS_NORMAL, ROUND_TOWARDS_ZERO): New.
(MODE_HAS_NANS, MODE_HAS_INFINITIES): Evaluate to false if
LARGEST_EXPONENT_IS_NORMAL for the given mode.
(MODE_HAS_SIGN_DEPENDENT_ROUNDING): False when ROUND_TOWARDS_ZERO.
* real.c (eadd1): Make rounding dependent on !ROUND_TOWARDS_ZERO.
(ediv, emul, eldexp, esqrt): Likewise.
(etoe113, etoe64, etoe53, etoe24, etodec, etoibm, etoc4x): Likewise.
(e24toe): Only check NaNs & infinities if !LARGEST_EXPONENT_IS_NORMAL.
(saturate): New function.
(toe53, toe24): Saturate on overflow if LARGEST_EXPONENT_IS_NORMAL.
(make_nan): Use a saturation value instead of a NaN if
LARGEST_EXPONENT_IS_NORMAL. Warn when this happens.
* fp-bit.c (pack_d): Saturate on NaN, infinite or overflowing
inputs if LARGEST_EXPONENT_IS_NORMAL. Represent subnormals as
zero if NO_DENORMALS. Only round to nearest if !ROUND_TOWARDS_ZERO.
(unpack_d): No NaNs or infinities if LARGEST_EXPONENT_IS_NORMAL.
(_fpmul_parts, _fpdiv_parts): Only round to nearest if
!ROUND_TOWARDS_ZERO.
