This patch refactors the sparc64 ifunc selector to a C implementation.
Also, the generic symbol is moved to its own implementation file
(s_isnan{f}-generic.S).
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
* sysdeps/sparc/sparc64/fpu/multiarch/Makefile (sysdeps_calls):
Add s_isnanf-generic and s_isnan-generic objects.
* sysdeps/sparc/sparc64/fpu/multiarch/s_isnan-generic.S: New file.
* sysdeps/sparc/sparc64/fpu/multiarch/s_isnanf-generic.S: Likewise.
* sysdeps/sparc/sparc64/fpu/multiarch/s_isnan.c: Likewise.
* sysdeps/sparc/sparc64/fpu/multiarch/s_isnanf.c: Likewise.
* sysdeps/sparc/sparc64/fpu/multiarch/s_isnan.S: Remove file.
* sysdeps/sparc/sparc64/fpu/multiarch/s_isnanf.S: Likewise.
