Joseph Myers fd3b4e7c8a Use libm_alias_ldouble for ldbl-128 functions.
This patch makes ldbl-128 functions use libm_alias_ldouble to define
function aliases.  float128_private.h is updated accordingly.  Most of
the ldbl-64-128 wrappers are removed as no longer needed with this
change (leaving those that involve versioning for functions in libc or
that shouldn't be exported from libm for _Float128 / _Float64x types
with the same format as long double).

Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by this patch.
