Fix for 823431: pt-query-advisor hangs on big queries

This was caused by a regex backtracking itself to a halt. The solution
was to add a positive lookahead that searches for the floating but mandatory
substrings that the regex needs; if those exist, then eventually it will
match, but if they don't, it'll fail quickly.
