Accessing item in orderedlist using non constant index returns AlgebricksException #773

What steps will reproduce the problem?
let $i := 1
let $b := ["hello", "world"]
return $b[$i]

What is the expected output? What do you see instead?
it should return the second item in the list, which is "world". It throws an 
exception: "get-item: item index cannot be negative! [AlgebricksException]"

For the record, this was a parser issue. Parser was only accepting literal 
expressions as the index. I fixed this issue in a611ac7575f0 by accepting all 
the expressions during parsing.
