The current version of SmiTag and SmiUntag was checking if the registers were the same, copying them if not and then untagging. We can avoid a branch and a check by having two versions of SmiTag and SmiUntag.

Almost everywhere, we use the ProcessedFeedback abstraction to query feedback in the compiler. The remaining exception is in handling RegExp, Object and Array literals. By bringing this in line with other feedback queries, we no longer need to serialize all feedback vector slots (possibly wasteful of memory), and offer a uniform way to pick up feedback everywhere.

With lazy feedback allocation, for functions that get OSRed we may not have feedback for the initial part of the functions since feedback vectors might be allocated after the function started executing. Hence we would not be able to optimize the function on the next call. This means we may have to OSR twice before we actually optimize function. This cl introduces OSR cache, so we could reuse the optimized code. One side effect of this cl is that the OSRed code won't be function context specialized anymore.

This CL removes the StoreBuffer and inserts slots into the RememberedSet directly from within the RecordWrite builtin. Only calls into C code when either the SlotSet-array or the bucket is not allocated. This avoids filling the store buffer up with duplicates or due to a write-heavy workload and then blocking the main thread on store buffer processing.
