ldbl-128ibm-compat: Provide nexttoward functions
The functions in the nexttoward family are special, in the sense that they always have a long double argument, regardless of their suffix (i.e.: nexttowardf and nexttoward have a long double argument, besides the float and double arguments). On top of that, they are also special because nexttoward functions are not part of the _FloatN API, hence __nexttowardf128 do not exist. This patch adds 4 new function implementations for the new long double format: __nexttoward_to_ieee128 __nexttowardf_to_ieee128 __nexttowardieee128 (as an alias to __nextafterieee128) Likewise, rename "long double" "_Float128" in shared ldbl-128 files to ensure correct type is used irrespective of ABI switches. Thank you to those who helped out with this patch: Co-Authored-By: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
