I was worrying about too many tags created if every bytecode has a tag. If it is 
the case, then I think only bytecodes that can throw exceptions need line number 
tags since line numbers are mostly useful in these situations. According to 
John's study, high percentages of bytecode can throw exceptions. We can skip 
some uncommon exceptions such as divided-by-zero. A list of important bytecodes 
in my mind are: new and new array instructions, method invocations, array 
accesses, field accesses, type casts.
