More aggressive DCE should honor debugger invariants

- A LINENUMEBER node is "dead" if the corresponding instruction interval
 contains at least one "dead" bytecode instruction
 and no live bytecode instructions

- Observable local variable lifetimes should be taken into account
 when determining if a NOP is required for debugger.
