The CSA implementation is a separate handler so that TF has the opportunity to reduce to a direct call, skipping some of the dispatching in the CloneObjectIC stub. This patch moves the looping over a source object's keys and values into the base CodeStubAssembler, so that it can be shared between ObjectAssignFast and CloneObjectIC_Slow. During each step of the loop, storing is delegated to a new SetPropertyInLiteral helper in KeyedStoreGenericGenerator, which performs a store without consulting the prototype chain, and automatically reconfigures accessors into data properties regardless of their attributes.

We had an optimization in Crankshaft where we would call into the megamorphic handler stub directly if an inline cache was already found to be megamorphic when it hit the optimizing compiler. This way we could avoid the dispatch overhead when we know that there's no point in checking for the other states anyways. However we somehow missed to port this optimization to TurboFan. Now this change introduces support to call into LoadIC_Megamorphic and KeyedLoadIC_Megamorphic directly (plus the trampoline versions), which saves quite a lot of overhead for the cases where the map/name pair is found in the megamorphic stub cache, and it's quite a simple change. We can later extend this to also handle the StoreIC and KeyedStoreIC cases if that turns out to be beneficial. This improves the score on the Octane/TypeScript test by around ~2% and the TypeScript test in the web-tooling-benchmark by around ~4%. On the ARES-6 Air test the steady state mean improves by 2-4%, and on the ARES-6 ML test the steady state mean seems to also improve by 1-2%, but that might be within noise. On a micro-benchmark that just runs `o.x` in a hot loop on a set of 9 different objects, which all have `x` as the first property and are all in fast mode, we improve by around ~30%, and are now almost on par with JavaScriptCore.

The fallback for {Pinsrd} and {Pextrd} for the non-avx and non-sse variant clobbered the {xmm0} register. This CL fixes this by storing the values on the stack and modifying them there instead. The alternative would have been to pass in a scratch register. But this path is not commonly used and we cannot express in the API whether the scratch register is needed or not. So we would sometimes have to spill a register to pass it as scratch register even though it is then unused.

There was a bug in WebAssembly.instantiate in the case where a CSP disallows WebAssembly compilation. In this case the promise returned by WebAssembly.instantiate was rejected immediately because of the CSP, but then compilation was started anyways, and the promise was resolved after compilation for a second time, which caused the crash. With this CL we do not start compilation if CSP disallows WebAssembly compilation.

This adds the ability to import exception into a module at instantiation time. Only a {WasmExceptionObject} that has been exported by another module instance can be imported, all other values are rejected. Note that currently there is no signature check being performed to make sure the imported exception matches the expected type. Also the identity of imported exceptions is not yet preserved. Furthermore the engine does not yet match thrown exception objects on a global level across modules. Hence imported exceptions will (wrongly) behave as completely new types within the module.

This inserts unreachable node after uncoditional deopt in bit-to-word conversion and wires it as an input to the dead-value. This fixes a problem, where a floating dead-value was inserted by a change of bit-to-word (which always fails because bit cannot be converted to word). Without the unrachable node (which this CL inserts in the effect chain after deopt), the dead value was scheduled before the uncoditional deoptimization and crash at runtime. Unfortunately, I do not know how to construct a test that does not end up in an infinite loop.
