This CL includes the following changes: - Avoid using `UniqueRegister` as much as possible - Try to group opcodes under Binary or Unary when possible Separate selectors are added to use `UniqueRegister` when necessary mainly when `Temp` registers are used. This is to make sure temp, dst and src registers are allocated differently and cannot be overwritten during codegen. Some codegen ops had to also be modified to avoid using `Temp` registers.

If the debugger is disabled for an isolate, we first remove all breakpoints for that isolate, and then tier up the module (if there is no other isolate that keeps it tiered down). During the first step, functions might get recompiled since the set breakpoints change. This is not needed in case we will tier-up the module afterwards anyway. It also triggers a DCHECK if we reinstall debugging code even though the module is already marked "tiered up". This CL avoids the installation of debugging if the module is not tiered down, and also slightly modified the condition for installing new code when tiered-up (to allow overwriting debugging code with non-debugging code even if it's the same tier).

JSHeapBroker::ReadFeedbackForCall() - it may be that the JSFunction we read in the feedback vector hasn't been store-ordered and is therefore unsafe to read. Therefore, we need to call the gc predicate to ensure safety. JSFunctionRef::feedback_vector() & raw_feedback_cell() - I was able to remove the TODO warning about uninitialized data visible from a direct read of these fields from the background. This is because we either store-order into those fields, or rely on a prior store-ordering. Additionally, FeedbackVectorRef and FeedbackCellRef are never-serialized objects, so their first encounter on the background thread is fine (we don't need to have seen and serialized them on the main thread first).

.. and the corresponding map cache. This cache was only used for CreateArray reductions, thus we mostly expect to see unmodified JSArray initial maps. These are already accessible from the native context and don't need to be cached separately. We may also see initial maps for custom JSArray subclasses. New map allocation may be necessary in this case if the requested elements kind differs from that of the current given initial map. Since we can't (easily) allocate on the background thread, we skip the optimization starting with this CL.

This avoids a DCHECK failure if we continue using the Assembler after code generation abortion. Even though it might not be the best style to still call methods on the Assembler after abortion, it's not a problem apart from the firing DCHECK, so we apply this simple fix instead of making sure to really abort everything immediately.

Added a parameter to Object::FitsRepresentation() to disallow coercion. Normally, when we ask if a Smi can "fit" into a Double representation we'd answer yes, because the Smi can be converted to a HeapNumber. However, from the compilers perspective, the object is found in a field with a particular representation. In this case, finding a Smi in a field with representation Double means something is awry. Therefore, it's useful for the compiler to be able to ask if the object fits the field without coercion.

When there are multiple entries into a deferred block region, ensure that we freeze the set of deferred spill virtual registers when we have processed the first entry point to that deferred block. This ensures that we don't add another vreg into the set of deferred spills, and then specify that that deferred spill slot is live across the whole deferred block, when it is only live from certain entry points.

This CL cleans up the trap handler code on POSIX before making additions for arm64 simulator support. In particular, - it extends a comment about restoring the signal mask before restoring the "thread in wasm" flag, and fixes the code to actually implement that again; - it renames "SigUnmaskStack" to "UnmaskOobSignalScope", to make the intent clear, and it moves the signal masking code to the constructor of that class; - it replaces a call to "IsThreadInWasm" by just reading "g_thread_in_wasm_code" to make it more transparent what is happening (note that the next instruction will just write to that flag); - it replaces an if block by another early exit for consistency; and lastly - it avoids curly braces for single-line conditions, to increase readability and to match the rest of V8.

This refactors the {GetMemOp} function once again: Instead of computing (mem_start + (offset_reg + offset_imm)), do compute ((mem_start + offset_imm) + offset_reg). This avoids an overflow in (offset_reg + offset_imm) when using 32-bit computations, which hides OOB memory accesses when relying on the trap handler. As a nice side-effect, this change makes the whole method a lot nicer to read. We also need to change {StoreTaggedPointer} now, which was relying on the inner working of {GetMemOp}. The new version makes the semantics more transparent at the cost of repeating some logic from (the previous version of) {GetMemOp}.

Now that code entries outlive our CodeMap, it's safe to avoid storing CodeMap metadata after the last active profiler stops. This simplifies lifecycle logic, and avoids retaining stale data.

Port fb28cfe6 Original Commit Message: So far, discarded size was maintained by the sweeper but not wired up anywere. Changes in this patch: - Wire up resident size in heap statistics collection. - Fix bugs in reporting committed and resident size. - Sweeper test: Enforce some internal details. The details should not not be checked broadly but be kept as a detail to the sweeper itself. - Stats collection: Test that committed and resident set size are reported and differ after discarding GCs.

Code event handler relies on having WasmEngine having an isolate, which happens during Snapshot::Initialize. Note that this fixes a crash (that the WasmEngine doesn't have an isolate), but does not get gdbjit integration with Wasm working yet (see https://crbug.com/v8/11908).

Most Torque-defined extern classes already use @generateCppClass. As Nico pointed out in [1], it would be nice to convert the remaining classes and remove this option. This change converts about a third of those remaining classes. I know that the future of Torque-defined classes is a subject of some debate right now, but I think that it's worth doing a few mechanical changes to reduce the existing variety of options.
