For GETLOCAL followed by POP where the POP has incoming jumps, we treated the operation as a dead use of the local. (We do this for normal 'JSOP_GETLOCAL POP' sequences because this bytecode is emitted at the head of scripts for each local, which screws up liveness information if not special cased. A JSOP_DEFLOCAL would be a nice opcode to have to simplify this stuff). This is correct to do, but broke register allocation invariants when merging state at the POP. http://hg.mozilla.org/projects/jaegermonkey/rev/29107a03d23d
