[issue43950] Include column offsets for bytecode instructions

[Mark Shannon]

Mark Shannon <mark at hotpy.org> added the comment:

The additional cost will not only be the line number table, but we need to store the line for exceptions that are reraised after cleanup.
Adding a column will mean more stack consumption.
