Fix sNaN handling in nearbyint on 32-bit sparc.
* sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Don't check for sNaN before float register is loaded with the incoming argument. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/s_nearbyint.S (__nearbyint): Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/s_nearbyintf.S (__nearbyintf): Likewise.
