Use libm_alias_float for x86_64. 

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes x86_64 libm function implementations use
libm_alias_float to define function aliases, or libm_alias_float_other
where the main name is defined with versioned_symbol.

Tested with the glibc testsuite for x86_64, and tested with
build-many-glibcs.py for all its x86_64 configurations that installed
stripped shared libraries are unchanged by the patch.
