Use libm_alias_double for i386.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes i386 libm function implementations use
libm_alias_double to define function aliases.

Tested with build-many-glibcs.py for all its i386 configurations that
installed stripped shared libraries are unchanged by the patch, as
well as running the full glibc testsuite for i686.
