sparc: refactor sparc64 rint{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_rint{f}-generic.S).
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
* sysdeps/sparc/sparc64/fpu/multiarch/Makefile
(libm-sysdep_routines): Add s_rintf-generic and s_rint-generic
objects.
* sysdeps/sparc/sparc64/fpu/multiarch/s_rint-generic.S: New file.
* sysdeps/sparc/sparc64/fpu/multiarch/s_rint.c: Likewise.
* sysdeps/sparc/sparc64/fpu/multiarch/s_rintf-generic.S: Likewise.
* sysdeps/sparc/sparc64/fpu/multiarch/s_rintf.c: Likewise.
* sysdeps/sparc/sparc64/fpu/multiarch/s_rint.S: Remove file.
* sysdeps/sparc/sparc64/fpu/multiarch/s_rintf.S: Likewise.
