Remove Function Calls For NaN-to-Number Comparisons With Greater/Less Than

[Geotale]

For greater/less than operators, normal operators (instead of comparison function calls) can be in these cases:

• The operator is lessThan, the left input can be a number or NaN, and the right input is a number that can't be NaN
• The operator is greaterThan, the left input is a number that can't be NaN, and the right input can be a number or NaN

This can be done because string comparisons with numbers and NaN in these scenarios will always return false (for example, "NaN" < "10000" is false, which is the same as NaN < 10000) If this is not done, then the compareLessThanSlow path is taken for each comparison with these values, assuming they include NaN

I've now realized that, by using !(val1 >= val2), and similarly with <=, you can completely remove all function calls for number + number or NaN comparisons.
