Use libm_alias_ldouble in math/.
This patch converts libm function implementations in math/ from using
weak_alias to using libm_alias_ldouble to define public function
names, in cases where it would be appropriate to define _Float128 /
_Float64x aliases for those functions as well (in cases where either
or both of those types exist and have the same ABI as long double).
This eliminates many ldbl-opt wrappers round these function
implementations.

Tested for x86_64, and with build-many-glibcs.py.  All installed
stripped shared libraries are unchanged except for libm.so on
powerpc64le.  As noted for a previous patch, powerpc64le's use of
ldbl-opt means various long double functions get defined using
long_double_symbol which gives them an explicit symbol version in the
object files, and this patch results in some such functions using
weak_alias instead (because powerpc64le never had a previous version
of these functions for long double = double); both produce a valid
libm.so with the same public symbols at the same versions, but macros
expanding to call weak_alias is cleaner in this case.
