This moves most of the logic contained in RegExpExecStub to CSA. Benefits are mostly easier readability and hackability, and removal of a large chunk of platform-specific assembly. Exit frame construction and the final call remain in RegExpExecStub. BUG=v8:5339,v8:592 Review-Url: https://codereview.chromium.org/2738413002 Cr-Commit-Position: refs/heads/master@{#43844}

Port the Call feedback machinery from the interpreter to the CallICStub as second step to unify the feedback collection. This removes a lot of hand-written native code, and makes the runtime miss handler obsolete. The next step will be to use the CallICStub from the interpreter as well.

Previously, when restarting a frame, we would rewrite all frames between the debugger activation and the frame to restart to squash them, and replace the return address with that of a builtin to leave that rewritten frame, and restart the function by calling it. We now simply remember the frame to drop to, and upon returning from the debugger, we check whether to drop the frame, load the new FP, and restart the function.

We turn a JSCallFunction node for f.apply(receiver, arguments) into a JSCallForwardVarargs node, when the arguments refers to the arguments of the outermost optimized code object, i.e. not an inlined arguments, and the apply method refers to Function.prototype.apply, and there's no other user of arguments except in frame states. We also replace the arguments node in the graph with a marker for the Deoptimizer similar to Crankshaft to make sure we don't materialize unused arguments just for the sake of deoptimization. We plan to replace this with a saner EscapeAnalysis based solution soon.

Literal arrays and feedback vectors for a function can be garbage collected if we don't have a rooted closure for the function, which happens often. It's expensive to come back from this (recreating boilerplates and gathering feedback again), and the cost is disproportionate if the function was inlined into optimized code. To guard against losing these arrays when we need them, we'll now create literal arrays when creating the feedback vector for the outer closure, and root them strongly in that vector.

This CL also cleans up related interface descriptors: 1) unused StoreTransitionDescriptor is removed and VectorStoreTransitionDescriptor is renamed to StoreTransitionDescriptor. 2) on ia32/x87 architectures slot and vector are passed on the stack (dispatcher/handlers cleanup will be addressed in a separate CL). These two stub ports have to be combined in one CL because: 1) without changing the StoreTransitionDescriptor TF was not able to compile them on ia32/x87 (because of lack of registers), 2) it was not possible to change the descriptor first because Crankshaft was not able to deal with the stack allocated parameters in case of a stub failure.
