This CL simplifies IC code since we no longer need to keep feedback slot indices in both Smi and IntPtr form and as a result it should improve overall performance of --no-opt mode on Octane by ~1%.

This replaces all typedefs that define types and not functions by the equivalent "using" declaration. This was done mostly automatically using this command: ag -l '\btypedef\b' src test | xargs -L1 \ perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg' Patchset 2 then adds some manual changes for typedefs for pointer types, where the regular expression did not match.

For global object property cells, we did not check that the map on the previous object is still the same for which we actually optimized. So the optimized code was not in sync with the actual state of the property cell. When loading from such a global object property cell, Crankshaft optimizes away any map checks (based on the stable map assumption), leading to arbitrary memory access in the worst case. TurboFan has the same bug for stores, but is safe on loads because we do appropriate map checks there. However mixing TurboFan and Crankshaft still exposes the bug.

This fully deprecates all uses of the RUNTIME_ASSERT macro and removes the macro and underlying logging function in question. All uses have been replaces with CHECK macros which crash safely even in production. It makes sure we discover abuse of runtime functions in the wild early and also abort the process safely. Breaking assumptions in any runtime function can no longer accidentally be caught by JavaScript.

Runtime asserts are were previously a bit annoying to debug, due to the lack of a useful error message, even in debug mode. This patch prints out some more information in debug mode for runtime assert failures while preserving their exception-throwing semantics. While we're at it, it requires a semicolon after RUNTIME_ASSERT macro invocations. ``` $ rlwrap out/Debug/d8 --allow-natives-syntax V8 version 5.1.0 (candidate) d8> %ArrayBufferNeuter(1) # # Runtime error in ../../src/runtime/runtime-typedarray.cc, line 52 # # args[0]->IsJSArrayBuffer() ==== C stack trace =============================== 1: 0xf70ab5 2: 0xadeebf 3: 0xadedd4 4: 0x2ef17630693b (d8):1: illegal access %ArrayBufferNeuter(1) ^ d8> ``` Also give the other 'illegal access' case (a special SyntaxError type) a more descriptive error message for its sole usage.

Adds a ForInPrepare Runtime function which returns a triple of cache_type, cache_array and cache_length. This requires adding support to CEntryStub to call runtime functions which return a ObjectTriple - a struct containing three Object* pointers. Also did some cleanup of the x64 CEntryStub to avoid replicated code. Replaces the interpreter's use of the ad-hock InterpreterForInPrepare Runtime function with ForInPrepare in preparation for fixing deopt in BytecodeGraphBuilder for ForIn (which will be done in a followup CL).

In a nutshell: The FILTER_KEY builtin is gone, and was replaced by a simple runtime call to ForInFilter, which does everything and is even cheaper (because FILTER_KEY used to call into the runtime anyway). And ForInFilter returns either the name or undefined, which makes it possible to remove the control flow construction from the AstGraphBuilder, and thereby make both the initialization and the per-loop code of for-in optimizable later (in typed lowering).

This enables adding more language modes in the future. For maximum flexibility, LanguageMode is a bitmask, so we're not restricted to use a sequence of language modes which are progressively stricter, but we can express the language mode as combination of features. For now, LanguageMode can only be "sloppy" or "strict", and there are STATIC_ASSERTS in places which need to change when more modes are added. LanguageMode is a bit like the old LanguageMode when "extended" mode was still around (see https://codereview.chromium.org/8417035 and https://codereview.chromium.org/181543002 ) except that it's transmitted through all the layers (there's no StrictModeFlag).
