This handles relational comparison operations (no equality yet) having number feedback during the early type-hint lowering (i.e. during graph construction).

This makes it no longer necessary to ensure that V8 and Blink have non-colliding tags, which makes it easier for them to evolve independently, and also makes the wire format more suitable for other V8 embedders, who would not necessarily be surveyed before V8 introduced a new tag that might collide with theirs.

When an instance of a constructor goes dictionary mode, this changes the initial map of that constructor to also be in dictionary mode. This avoids spurious hidden class creation, that also results in IC misses.

This extends the existing typer for JS-level comparisons to also be applied on simplified-level number comparisons. Now that nodes having such operators are introduced early during graph construction, precise type information has become more important.

Nodes having the {Throw} operator are just used as terminators for control-flow leaving the function body with an exception completion, they turn into basic-block terminators within the schedule. Actually raising an exception is done solely via runtime calls. Hence {Throw} nodes no longer need any value input.

Don't just blindly bake in CallIC feedback in the JSCallReducer, but instead try to estimate first whether it makes sense to bake it in (and risk potential eager deoptimization exits). We already didn't use the CallIC feedback when the call target is a known constant, but we should also not use it if the target is a JSCreateClosure node or a Phi of known constants / JSCreateClosure nodes.

Calling AstNode::Print() from within gdb, e.g. during bytecode generation, sometimes results in a CHECK failure due to handle dereferencing being disallowed. This is very frustrating. Since this function is purely for debugging and not called anywhere in the code base, I'm now explicitly adding an AllowHandleDereference scope to it.

Currently, ArrayIncludes handles the hypothetical case of an array with a fast ElementsKind and non-SMI length. This should not happen (and is checked against in JSArray::JSArrayVerify of objects_debug.cc). Therefore this CL replaces that handling with a CSA_ASSERT that the length is indeed SMI. The CL also simplifies loading of the (SMI) length on 64 bit architectures by using LoadAndUntagObjectField instead of LoadObjectField+SmiToWord.
