This CL factors the parts of the JSGraph that only depend on the machine part of JSGraph into a separate base class, MachineGraph. This helps separate the two layers and also allows the MachineGraph to be constructed without an Isolate, which is needed for fully asynchronous compilation, a goal for WASM.

- In debug builds, 'assert(<expr>)' evaluates and aborts execution if the provided Torque expression is false at runtime. assert(<expr>) supports the same set of expressions protocols as Toruqe's if statement, i.e. both bool values and BranchIf- style tests. Upon failure, the assertion prints the Torque source code of the failed expression, not the generated CSA code. - 'unreachable' calls CSA's Unreachable() and signals to Torque that code execution cannot continue (i.e. its statement returns the 'never' type). In debug builds, the line number and position of the statement are printed before breaking. - 'debug' calls CSA's DebugBreak(). In debug builds, the line number and position of the 'debug' are printed before breaking.

This makes sure that allocations of {HeapNumber} objects happening in the JS-to-Wasm and Wasm-to-JS wrappers are ordered with respect to changes of the {trap_handler::IsThreadInWasm} predicate. Otherwise the compiler can (and will) move the allocations across changes of this predicate and cause safety checks to fire.

On arm64, we had {RegisterBase::bit} (defined in assembler.h) and {CPURegister::bit} (defined in assembler-arm.h). {CPURegister} inherits from {RegisterBase}. The two methods methods have different behaviour on the special {no_reg}, which is only relied on in very few places. This CL fixes these places to avoid the use of {no_reg}, and removes the overwritten method.

Since 94ce16b7, when loading an iterator from null or undefined, we generate the error message "x is not iterable" instead of the unwieldy "Cannot read property 'Symbol(Symbol.iterator)' of undefined". However Runtime::GetObjectProperty, which is used as slow path by LoadICs, did not check for this case, leading to different messages being generated depending on IC state.

Port 519bd47f Original Commit Message: With the exception of the InterpreterEntryTrampoline, all builtins are now isolate-independent and can be embedded into the binary. This CL updates the corresponding list and also contains a few smallish tweaks to support having these builtins off the heap: * wasm: copy the off-heap builtin, not its trampoline. * Code::contains: support off-heap builtins. * JSFunction::is_compiled: compare builtin index instead of identity (this is relevant during mksnapshot when we transition from the on-heap builtin to its off-heap representation + the trampoline). * Remove old DCHECKs. * A few tweaks in macro-assembler ports that have snuck in recently.

Port ab9e0124 Original Commit Message: Original CL: https://crrev.com/c/1018468 During code generation, we generate self-references (i.e. references to the Code object currently being generated) as references to a temporary handle. When the final Code object has been allocated, the handle's location is fixed up and RelocInfo iteration fixes up all references embedded in the generated code. This adds support for this mechanism to the builtins constants table builder. CodeObject() is now a new handle pointing to a dedicated self-reference marker in order to distinguish between self-references and references to undefined. In Factory::NewCode, we patch up the constants table.
