This patches consolidates all the powerpc ceil{f} implementations on
the generic sysdeps/powerpc/fpu/s_ceil{f}. The generic implementation
uses either the compiler builts for ISA 2.03+ (which generates the frip
instruction) or a generic implementation which uses FP only operations.
It adds a generic implementation (round_to_integer.h) which is shared
with other rounding to integer routines. The resulting code should be
similar in term os performance to previous assembly one.
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).

Continuing the move to use, within libm, public names for libm
functions that can be inlined as built-in functions on many
architectures, this patch moves calls to __ceil functions to call the
corresponding ceil names instead, with asm redirection to __ceil when
the calls are not inlined.
Tested for x86_64, and with build-many-glibcs.py.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes powerpc libm function implementations use
libm_alias_float to define function aliases.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.
