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.
