New version if COMPAT_SIMODE_TRAPPING_ARITHMETIC.
(__addvdi3): Rename to __addvDI3.
(__subvsi3): Rename to __subvSI3. Use word type for the result.
New version if COMPAT_SIMODE_TRAPPING_ARITHMETIC.
(__subvdi3): Rename to __subvDI3.
(_mulvsi3): Rename to _mulvSI3.
New version if COMPAT_SIMODE_TRAPPING_ARITHMETIC.

(__absvsi2): Rename to __absvSI2.
New version if COMPAT_SIMODE_TRAPPING_ARITHMETIC.
(__absvdi2): Rename to __absvDI2.
* libgcc2.h (64-bit targets): Define COMPAT_SIMODE_TRAPPING_ARITHMETIC.
(__absvSI2, __addvSI3, __subvSI3, __mulvSI3, __negvSI2, __absvDI2,
__addvDI3, __subvDI3, __mulvDI3, __negvDI2): Define to the appropriate
symbol and declare.
(__absvsi2, __addvsi3, __subvsi3, __mulvsi3, __negvsi2): Declare if
COMPAT_SIMODE_TRAPPING_ARITHMETIC.
