So far, we decoded instructions with the 0xFB prefix as two-byte, i.e. a single "u8" byte following the prefix. This patch changes that to 0xFB + LEB, which is how all prefixed instructions are supposed to do it. Currently this makes a difference only for the stringref proposal (instructions 0x80 through 0xb3). It has the unfortunate consequence that all stringref instructions need three bytes for now. We expect them to go back to a two-byte encoding scheme (while remaining LEB compliant) when their final encoding is decided.

Port c5d48121 Original Commit Message: This CL adds the shared barrier to the RecordWrite builtin which is used in generated code for builtins, interpreted and optimized code. The out-of-line part of the barrier now checks whether either the POINTERS_TO_HERE_ARE_INTERESTING or the IN_SHARED_HEAP bit is set in the value object's page flags. Outside of marking the RecordWrite builtin now needs to check whether to insert into the generational or shared remembered set. Inserting into the shared remembered set will always call into C++ code. During marking the RecordWrite builtin now also needs to check whether this store created an old-to-shared pointer.

Two inputs might alias the same node. If one input is assigned any location before the second input is assigned a register, we might have two inputs in the node in different locations. Assigning any location later forces the inputs to point to the same location (either a register or a stack slot).

This CL removes the bailout when trying to collect the scope info for the class member initializer function. While this might not have worked previously, now we only need to tweak the scope search slightly to fix this. Class member initializer functions never have their own context but instead us the class context. That means that most of the logic in debug-scopes.cc doesn't really matter and we only need to initialize the ScopeIterator properly with the class context and the member initializer JSFunction. Note that this still does not fully fix bug 1350842. That is because we still run into a DCHECk when paused at a `new class { ... }` statement. We'll fix that in a separate CL.

StringConstantXXX were introduced when we switched to concurrent compilation, as a way to build strings in Turbofan in a background thread, without having to actually allocate them on the main heap from the background. See https://crrev.com/c/1221807. Now that we have local heaps, we can actually allocate strings from the background, making StringConstantXXX useless. Moreover, we would fold constant string concatenations into ConsString, which sounds a bit dubious for performance. Now, small constant string concatenations will be folded into SeqStrings, while larger ones will remain ConsString, just to avoid the quadratic worst-case.
