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. * math/s_fmal.c: Include <libm-alias-ldouble.h>.
