sparc: refactor sparc64 isnan{f} selector to C
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.
