The Annex G special cases only occur in cases where NaN is returned. Since
GCC's MPC infrastructure already backs out when encountering NaN values,
using MPC here means folding doesn't occur and the correct Annex G values
are calculated by libgcc at runtime.
These cases still need to work in static initializers, so you may need to avoid the MPC infrastructure backing out when evaluating static initializers, and add tests of them to your testcase.
