Ues libm_alias_double for various powerpc functions.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch various powerpc functions use libm_alias_double to
define function aliases (with consequent removal of the need for local
compat symbol handling).  (The present patch excludes the changes to
some functions where such changes could result in differences in
installed stripped shared libraries because of changes to the exact
ordering or properties of symbols in individual .os files.)

Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged for all its hard-float powerpc configurations.
