Hmm, I wonder whether this one shouldn't really be:
if (mips_abs == MIPS_IEEE_754_2008 || !HONOR_NANS (V2SFmode))
as even though not explicitly specified for an ABS2008 implementation
that also supports the MIPS-3D ASE, I'd say ABS.PS is supposed to be
consistent with ABS.D and ABS.S and respect FCSR.ABS2008.
