sparc: refactor sparc32 llrint{f} selector to C
This patch refactors the sparc32 ifunc selector to a C implementation. Also, the generic symbol is moved to its own implementation file s_llrint{f}-generic.S). Checked on sparc64-linux-gnu and sparcv9-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_llrintf-generic and s_llrint-generic. * sysdeps/sparc/sparcv9/fpu/multiarch/s_llrint-generic.S: New file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_llrint.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_llrintf-generic.S: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_llrintf.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_llrint.S: Remove file. * sysdeps/sparc/sparc32/sparcv9/fpu/multiarch/s_llrintf.S: Likewise.
