On x64 hardware, round-trip uint64_t&rarr;double&rarr;uint64_t conversions
fail for values greater than UINT64_MAX-2047.  This caused the SQLite
text-to-float converter routine to give incorrect results for values
between '1.8446744073709550592eNNN' and '1.8446744073709551609eNNN' for any
exponent NNN. Fixed by this check-in.
