JM: Remove tracerecursion
Much of the tracerecursion complication stemmed from mitigating trace transition costs. It actually swallowed interpreter frames on-trace to avoid leaving the JIT. Integrating this with the method JIT is very tricky. The method JIT is fast enough for now, and will get faster. Trace-recursion served its purpose and will hopefully be reborn in a world where the tracer stack overlays the mjit/interpreter stack, and JSStackFrames aren't hugeonormous. For now, it's a lot of code that is very difficult to maintain. RIP.
Remove more remnants, JSOP_TRACE after CALL (requires fixing a lot of debug tests that hardcode bytecode offsets) and some EnterFrame cruft.
