  [native_pbc] finish cvt_num16_num8 fix #1193

move the old cvt_num16_num8 code for true __float128 to cvt_num16_num8_be,
where it is really used in non-powerpc long doubles.

Closes GH #1193.
Also fixed a small codingstd problem.

TODO: darwin ppc long-double, and many more conversions. See `native_pbc2` for that.
