    sparc: refactor sparc64 __mpn_add_n 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
    add_n-generic.S).
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
    
    	* sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines):
    	Add add_n-generic.
    	* sysdeps/sparc/sparc64/multiarch/add_n-generic.S: New file.
    	* sysdeps/sparc/sparc64/multiarch/add_n.c: Likewise.

    sparc: refactor sparc64 __mpn_sub_n 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
    sub_n-generic.S).
    
    Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
    
    	* sysdeps/sparc/sparc64/multiarch/Makefile (sysdep_routines):
    	Add sub_n-generic.
    	* sysdeps/sparc/sparc64/multiarch/sub_n-generic.S: New file.
    	* sysdeps/sparc/sparc64/multiarch/sub_n.c: Likewise.
    	* sysdeps/sparc/sparc64/multiarch/sub_n.S: Remove file.
