powerpc: Refactor powerpc32 lrint/lrintf/llrint/llrintf

This patches consolidates all the powerpc llrint{f} implementations on
the generic sysdeps/powerpc/powerpc32/fpu/s_llrint{f}.

Checked on powerpc-linux-gnu (built without --with-cpu, with
--with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch),
powerpc64-linux-gnu (built without --with-cpu and with --with-cpu=power5+
and --disable-multi-arch).

	* sysdeps/powerpc/fpu/s_lrintf.S: Remove file.
	* sysdeps/powerpc/powerpc64/fpu/s_lrintf.c: Move to ...
	* sysdeps/powerpc/fpu/s_lrintf.c: ... here.
	* sysdeps/powerpc/powerpc32/fpu/Makefile
	[$(subdir) == math] (CFLAGS-s_lrint.c): New rule.
	* sysdeps/powerpc/powerpc32/fpu/s_llrint.c (__llrint): Add power4
	optimization.
	* sysdeps/powerpc/powerpc32/fpu/s_llrintf.c (__llrintf): Likewise.
	* sysdeps/powerpc/powerpc32/fpu/s_lrint.S: Remove file.
	* sysdeps/powerpc/powerpc32/fpu/s_lrint.c: New file.
