The PowerPC 64-bit ABI is defined to pass __float128 values in 128-bit vector
registers and return _float128

When converting IBM long double to __int128, large values that overflow are not
returning the expected values.
To be consistent with double to long conversions the conversion

Well the language spec may not specify. But I can ask the platform to be
consistent with itself. For PowerISA I would expect long double -> __int128 to
be consistent with double -> long, which saturates
