Do not attempt the LIKE optimization on a column with numeric affinity if the rhs of the operator begins with whitespace. Fix for ticket [fd76310a5e]. (check-in: 94b58ab059 user: dan tags: trunk)

When casting string values into numeric and the string has a prefix that looks like a number but total string is not a well-formed number, then take extra care that the result is either integer or real depending on what the prefix looks like. Fix for tickets [e8bedb2a184001] and [4c2d7639f076aa]. (check-in: 67a68af557 user: drh tags: trunk)
