Continuing the process of setting up common macros for libm function aliases, with a view to using them to define _FloatN / _FloatNx aliases in future, this patch adds a libm_alias_float128 macro and uses it in the type-generic templates. (_Float128 functions will end up with _Float64x aliases on powerpc64le, but not on x86_64/x86/ia64 because _Float64x has long double format there, and the macro will provide a single place for the conditionals for that choice, as well as for once ldbl-128 functions always build *f128 and need conditionals for whether to have *l aliases.) Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/libm-alias-float128.h: New file. * sysdeps/generic/math-type-macros-float128.h: Include <libm-alias-float128.h>. [!declare_mgen_alias] (declare_mgen_alias): Define macro.
