Use libm_alias_double for ia64. 

Continuing the preparation for additional _FloatN / _FloatNx function
aliases, this patch makes ia64 libm function implementations use
libm_alias_double to define function aliases.  The same approach is
followed as with the corresponding long double patch: the
ia64-specific macros are left unchanged, with calls to
libm_alias_double_other being added in most cases and
libm_alias_double itself being used in only a few places.

Tested with build-many-glibcs.py for ia64-linux-gnu that installed
stripped shared libraries are unchanged by the patch.
