This removes the obsolete use of FrameStateBeforeAndAfter when visiting compare operations. None of the operators in question require a "before" frame state by now. R=jarin@chromium.org Review-Url: https://codereview.chromium.org/2144063003 Cr-Commit-Position: refs/heads/master@{#37771}

This is a requirement to replace AstNode vtable with a NodeType tag. In a second CL (https://codereview.chromium.org/2142233003/) I switch over that tag rather than double dispatch. With additional packing in a third CL there's roughly 8 byte reduction for almost all AstNode types, and for some even more.

This CL introduces explicit LoopExit control nodes at loop exits. We also attach explicit value renames (LoopExitMarker) and effect rename (LoopExitEffect) to each loop exit. This is in preparation to loop peeling, which will replace LoopExit, LoopExitMarker and LoopExitEffect with Merge, Phi and EffectPhi respectively. At the moment, we insert loop exit at every return, break, continue and locally caught throw. We do not yet handle uncaught throws (including error throws, such as ReferenceError).

This removes the fallback path in question. Now the {AstNumbering} phase is the only phase deciding whether Crankshaft is supposed to be disabled or not. This in turn simplifies reasoning about the paths through the compilation pipeline. We can decide early whether we want Ignition to kick in depending on whether Crankshaft is enabled or not.

Original commit message: Also, CodeGenerator::MakeCodeEpilogue now accepts an optional pointer to a EhFrameWriter and will attach unwinding information to the code object when passed one. Reason for reverting: The STATIC_CONST_MEMBER_DEFINITION in eh-frame-writer-unittest.cc causes a compiler error on V8 Win64 - clang buildbot. Removing that bit.

Simulators use separate stacks for C++ and JS. JS stack overflow checks are performed whenever a JS function is called. However, it can be the case that the C++ stack grows faster than the JS stack, resulting in an overflow there. Add a check here to make that less likely.

This CL is just a rebase of the original CL (https://codereview.chromium.org/2150523002). The reason for reverting was: Dependency of the roll unblocking revert https://codereview.chromium.org/2147883003/. Original message: The self reference requires the allocation of a handle in the macro assembler, which is not possible if we instantiate the macro assembler in a worker thread.
