Use libm_alias_float for i386.

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes i386 libm function implementations use
libm_alias_float (or libm_alias_float_other in cases where the main
symbol name is defined with versioned_symbol) 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.
