DFG should be able to optimize foo.apply(bar, arguments)

Reviewed by Gavin Barraclough.
        
Merge r116912 from dfgopt.
        
Enables compilation of op_jneq_ptr and some forms of op_call_varargs.
        
Also includes a bunch of bug fixes that were made necessary by the increased
pressure on the CFG simplifier.
        
This is a 1-2% win on V8.
