float128: Extend the power of ten tables
Update the power of ten tables used by the common implementation when long double is not the most expressive real type. * stdlib/fpioconst.h: Include bits/floatn.h. (FPIOCONST_HAVE_EXTENDED_RANGE): New macro for testing how big the power of ten table should be. (FPIOCONST_POW10_ARRAY_SIZE): Use larger table if above is true. * stdlib/fpioconst.c (__tens): Use FPIOCONST_HAVE_EXTENDED_RANGE to include larger tables when _Float128 support is enabled. (_fpioconst_pow10): Likewise.
