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. * sysdeps/i386/fpu/s_asinh.S: Include <libm-alias-double.h>.
