Rationalize array profiling for out-of-bounds and hole cases
https://bugs.webkit.org/show_bug.cgi?id=105139
Reviewed by Geoffrey Garen.
This makes ArrayProfile track whether or not we had out-of-bounds, which allows
for more precise decision-making in the DFG.
Also cleaned up ExitKinds for out-of-bounds and hole cases to make it easier to
look at them in the profiler.
Slight speed-up (5-8%) on SunSpider/crypto-md5.
