DFG should be able to optimize foo.apply(bar, arguments)
​https://bugs.webkit.org/show_bug.cgi?id=86306

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.
