powerpc: floor/floorf refactor
This patches consolidates all the powerpc floor{f} implementations on the generic sysdeps/powerpc/fpu/s_floor{f}. The generic implementation uses either the compiler builts for ISA 2.03+ (which generates the frim instruction) or a generic implementation which uses FP only operations. The IFUNC organization for powerpc64 is also change to be enabled only for powerpc64 and not for powerpc64le (since minium ISA of 2.08 does not require the fallback generic implementation). 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/fpu/round_to_integer.h (set_fenv_mode): Add FLOOR option. (round_mode): Add definition for FLOOR. * sysdeps/powerpc/fpu/s_floor.c: New file. * sysdeps/powerpc/fpu/s_floorf.c: Likewise. * sysdeps/powerpc/powerpc32/fpu/s_floor.S: Remove file. * sysdeps/powerpc/powerpc32/fpu/s_floorf.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floor-power5+.S: Remove file. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floor-ppc32.S: Likewise * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floorf-power5+.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floorf-ppc32.S: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floor-power5+.c: New file. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floor-ppc32.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floorf-power5+.c: Likewise. * sysdeps/powerpc/powerpc32/power4/fpu/multiarch/s_floorf-ppc32.c: Likewise. * sysdeps/powerpc/powerpc32/power5+/fpu/s_floor.S: Remove file. * sysdeps/powerpc/powerpc32/power5+/fpu/s_floorf.S: Remove file. * sysdeps/powerpc/powerpc64/be/fpu/multiarch/Makefile (libm-sysdep_routines): Add s_floor-power5+, s_floor-ppc64, s_floorf-power5+, and s_floorf-ppc64.
