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.

While these instructions accept memory operands, only one operand
may be a memory operand. Giving two operands xm constraints gives
the compiler the option of using memory for both operands, which
would result in invalid assembly code. Using x for all operands is
more appropriate, as most x86_64 calling conventions will pass the
arguments in registers anyway.
