[APFloat] Added unittest for APFloat.subtract that checks special cases, result categories, and result status.

// Test Special Cases against each other and normal values.
// TODOS/NOTES:
// 1. Since we perform only default exception handling all operations with
// signaling NaNs should have a result that is a quiet NaN. Currently they
// return sNaN.
// 2. It seems that sub(-x, NaN) = -NaN but sub(NaN, -x) = NaN. This is an
// inconsistency that should be looked into. IEEE-754R specifies that the
// interpretation of the sign of NaN is unspecified. We should always have NaN
// be positive since that is one less thing for the compiler to deal with.
