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

The IFUNC support is also moved only to powerpc64 only, since for
powerpc64le generic implementation resulting in optimized code.

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-cp and with --with-cpu=power5+
and --disable-multi-arch).

	* sysdeps/powerpc/powerpc64/be/fpu/multiarch/Makefile
	(libm-sysdep_routines): Add s_llrint-power8, s_llrint-power6x, and
	s_llrint-ppc64.
	(CFLAGS-s_llrint-power8.c, CFLAGS-s_llrint-power6x.c): New rule.

Look good to me.  Thanks

Thanks for doing this.

For reference, here's the code that's generated on a powerpc64 build
targetting power4 (--with-cpu=power4 seems to be used on many distros):

  000000000007e880 <.__llrint_power8>:
    7e880:       fc 20 0e 5c     fctid   f1,f1
    7e884:       7c 23 00 66     mfvsrd  r3,vs1
    7e888:       4e 80 00 20     blr

  000000000007e8a0 <.__llrint_power6x>:
    7e8a0:       fc 20 0e 5c     fctid   f1,f1
    7e8a4:       7c 60 0d be     mftgpr  r3,f1
    7e8a8:       4e 80 00 20     blr

  000000000007e8c0 <.__llrint_ppc64>:
    7e8c0:       fc 20 0e 5c     fctid   f1,f1
    7e8c4:       d8 21 ff f8     stfd    f1,-8(r1)
    7e8c8:       60 00 00 00     nop
    7e8cc:       60 00 00 00     nop
    7e8d0:       60 00 00 00     nop
    7e8d4:       e8 61 ff f8     ld      r3,-8(r1)
    7e8d8:       4e 80 00 20     blr

powerpc64le doesn't suffer from this store-load scenario, since it is
only available for power8 and newer.
