David Majnemer 45f3263c6f [APFloat] Properly implement DoubleAPFloat::convertFromAPInt 
The old implementation converted to the legacy semantics, inducing
rounding and not properly handling inputs like (2^1000 + 2^200) which
have have more precision than the legacy semantics can represent.

Instead, we convert the integer into two floats and an error.  The error
is used to implement the rounding behavior.

Remove related dead, untested code: convertFrom*ExtendedInteger
