This was previously landed in commit 8599f5f, but failed the
collections mjsunit test on ia32 with --deopt-every-n=1. The fixed
patch adds a ClearFlag(HValue::kCanOverflow) call after every
arithmetic operation, which should remove all the deopt points in these
intrinsics.
Ideally, it seems like there should be a way to verify that there are
no deopt points for these inline optimized functions, since there's
nothing to deopt to. But I don't currently know of such a thing.

Blink already has code for handling invalid cached data. The attached test
ensures that cached data is gracefully rejected if it cannot be used.
This also unifies parser cache and code cache handling.

When compiling with the macro DCHECK_ALWAYS_ON defined, DCHECKs and
supporting code gets compiled and enabled.

Reason for revert:
Deopt fuzzer reports that something's still broken, reverting until
I can create a minimal repro.

This introduces Hydrogen for %_GetPrototype. The code falls back on
runtime if the object needs access checks or if its prototype is a

Original commit message:
This combines Map::DoneInobjectSlackTracking and Map::ConstructionCount into one more generic 4-bit counter.
Counter values from 15 down to 8 are used for in-object slack tracking, values from 7 down to 0 are free to be used for a new counter when in-object slack tracking is inactive
