allow string concat in like

[sgress454]

Switches the order of precedence in the like op so that it checks for comaprison_expr before literal, so that it if a string concatenation like

SELECT * FROM file WHERE path LIKE 'C:' || CHAR(92) || 'Users' || CHAR(92) || 'example.txt';

is present, it grabs the whole thing instead of just stopping at 'C:' and leaving an unparsed || CHAR(92) || 'Users' || CHAR(92) || 'example.txt'; at the end of the query causing a syntax error.
