Use libm_alias_ldouble macros in sysdeps/ia64/fpu.

Continuing the preparation for additional _FloatN / _FloatNx aliases,
this patch makes long double functions in sysdeps/ia64/fpu use
libm_alias_ldouble macros, so that they can have _Float64x aliases
added in future.

Most ia64 libm functions are defined using ia64-specific macros in
libm-symbols.h.  These are left unchanged, with libm-alias-ldouble.h
included from libm-symbols.h (and the expectation that other
libm-alias-*.h headers will be included from there as well in future),
and libm_alias_ldouble_other then being used in most cases to define
aliases for any additional types (currently the empty set).  Functions
that used weak_alias are converted to use libm_alias_ldouble.

Tested (compilation only) with build-many-glibcs.py for ia64,
including that installed stripped shared libraries are unchanged by
the patch.
