Force parser to send information about current column number.

Add new member in all statements nodes which suppose to be a
column number from parser. All calls to setLoc were changed, they
should pass 2xline number (first and last line) and column number of
current "cursor"(token?) position.
Develop op_debug opcode to contain column number.
