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. * sysdeps/ieee754/float128/float128_private.h: Include <libm-alias-ldouble.h> and <libm-alias-float128.h>.
