Likewise, add documentation to the macro in the common bits/long-double.h header. This is effectively V2 of [2]. Per the feedback from Joseph [1]. Good comments and a more self-explanatory macro name will be very helpful when this macro is able to assume a non-zero value. [1] [2] ---8<--- Improve the commentary to aid future developers who will stumble upon this novel, yet not always perfect, mechanism to support alternative formats for long double. Likewise, rename __LONG_DOUBLE_USES_FLOAT128 to __LDOUBLE_REDIRECTS_TO_FLOAT128_ABI now that development work has settled down.
