fix strtod int optimization in non-nearest rounding mode
the mid-sized integer optimization relies on lnz set up properly to mark the last non-zero decimal digit, but this was not done if the non-zero digit lied outside the KMAX digits of the base 10^9 number representation. so if the fractional part was a very long list of zeros (>2048*9 on x86) followed by non-zero digits then the integer optimization could kick in discarding the tiny non-zero fraction which can mean wrong result on non-nearest rounding mode. strtof, strtod and strtold were all affected.
