This CL removes unnecessary code duplication in the fuzzer code. Instead of having special testing functions to compile and instantiate a WebAssembly module, we now just call SyncCompile and SyncInstantiate. This also fixed a problem when the fuzzer generated a GrowMemory instruction.

This adds support for materializing objects of {JSGeneratorObject} type during deoptimization. Cases where soft-deopts remove any escaping use of the implicit generator object can cause it to be escape analyzed.

Explicitly set argument for use_cfi_recover introduced in: https://codereview.chromium.org/2920963002 This retains the behavior we had in GYP: Print useful diagnostics, but crash to make the errors show up. Also set use_cfi_cast=true. In gyp we've set this by default: -fsanitize=cfi-derived-cast -fsanitize=cfi-unrelated-cast In GN it now lives behind the use_cfi_cast flag.

Only the CompilationCache doesn't actually specialize the table to the point where it knows how to hash stored keys. This moves the virtual HashForObject down from HashTableKey to CompilationCacheKey, and moves previous virtual implementations to the respective shapes.

The instanceof cache was initially introduced to speed up x instanceof y where y is always the same constructor and x is always an object with the same map. With the introduction of ES2015's @@hasInstance and the Function.prototype[Symbol.hasInstance] handler (which calls into OrdinaryHasInstance), this already became quite useless. It doesn't seem to provide any real value (not sure it ever did for real), but it's getting in the way of some useful refactorings (i.e. sharing logic between OrdinaryHasInstance and Object.prototype.isPrototypeOf for example). So this CL completely removes the leftover bits of the instanceof cache, including the GC and SetPrototype logic.

Port af76779a Original Commit Message: This splits the monolithic Apply builtin into several smaller builtins, namely CallVargargs and ConstructVarargs, which accept a length and a FixedArray of elements and deal with the actual stack manipulation, and CallWithArrayLike / ConstructWithArrayLike that deal with getting the elements from the receiver (for Function.prototype.apply, Reflect.apply and Reflect.construct), which can now be written using the CSA. The idea is that these builtins can be reused by TurboFan directly in the future when we optimize apply better, and that we can also reuse the core logic in the handling of spread calls/constructs.

In some [1] cases where a lexical declaration is not allowed, ASI will cause a `let` at the end of a line to be interpreted as an identifier. A recent patch [2] to fix up the error messages from misplaced `let` usage was a little overzealous in triggering the error, throwing a SyntaxError in this edge case. This patch restores the ASI behavior, which is permitted in JSC and SpiderMonkey as well. Thanks to a test262 test from Andre Bargull for raising this issue.
