Add a new late escape analysis pass to JS late optimizations. The new pass simply removes allocations that are not used (besides initializing stores to the object).

After AssertNoTypedSlotsInFreeMemory being a CHECK for some time now to get more test coverage, turn this into a DCHECK again. This CL also renames the methods used by the sweeper to clear typed slots in free memory. It was previously called "invalid slots" but IMHO that could be a bit misleading, since this isn't about object slot invalidation (where we also filter slots) but only really about slots in free memory.

The method is already misleading, as with dynamic tiering the "top tier" is defined to be the same as the "baseline tier" (i.e. Liftoff). Hence the method does not do what you would expect it to do. Fixing it to wait for all functions to be compiled with TurboFan would result in a deadlock, if we do not also trigger tier-up of all functions. Hence remove the method.

Some tests disabled dynamic tiering in order to actually serialize TurboFan code. This makes the tests a bit simpler, but does not reflect real-world usage. This CL enables dynamic tiering in those tests and when needed executes the code until tier-up was observed.

To eliminate unnecessary move instructions from register to fixed register. We check the fixed register hint for operands in move gaps when building LiveRanges. If a to_operand has a hint_operand (with fixed register), then set the hint_operand for from_operand too. This can avoid the register allocator ignore hint information about fixed register.

The fuzzer runs the same wire bytes through the streaming decoder and through synchronous compilation, and compares the result. In particular, if one fails, then also the other should fail.

Replace all usages of UPDATE_WEAK_WRITE_BARRIER with UPDATE_WRITE_BARRIER. The barrier wasn't hot, so the additional branch for the marking barrier shouldn't be a problem. Performing the marking barrier could in theory cause more floating garbage. However in this case the write barrier is only run once directly after e.g. allocating a Code or NativeContext object. Since UPDATE_WEAK_WRITE_BARRIER only skips the marking barrier, we should only observe different behavior when marking is on. But since we already have black allocation for objects in old space, we will not cause additional floating garbage. In case of performance regression, we should also be able to replace those usages with SKIP_WRITE_BARRIER, since NativeContext and Code objects are never allocated in the young generation, so running the generational barrier shouldn't be necessary. It's just hard to DCHECK that SKIP_WRITE_BARRIER is valid here.

If the optimized code is deoptimized and the deoptimized exit offset is inside of the optimized OSR code related loop, the optimized OSR code is also out of date, remove the optimized OSR code, it will avoid hit the optimized OSR code and soon later deoptimization of the optimized OSR code. This CL will reduce deoptimization. E.g. Deoptimization of JetStream2 case navier-stokes function addFields is reduced from twice to once.
