Assertion failure: !fe->data.inRegister(), at FrameState-inl.h:949

Revision aec367836312, 32-bit OS X.
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.
