This includes the following changes: - Limit code space to 128 MB. - Use direct branches wherever possible. - Where not possible, continue using load literal followed by an indirect branch. - Sort RelocInfo by target_address_address for the serializer, since mixing load literal instructions and branch instructions messes up that order. - Ensure we always wipe out targets in the serializer (not just for the snapshot) in order to be able to distinguish between constant pool entries and branch instructions.

The "Address" type is V8's general-purpose type for manipulating memory addresses. Per the C++ spec, pointer arithmetic and pointer comparisons are undefined behavior except within the same array; since we generally don't operate within a C++ array, our general-purpose type shouldn't be a pointer type.

This change makes lifetime management of WasmCode much simpler. By using the WasmInstanceObject as the context for WASM code execution, including the pointer to the memory base and indirect function tables, this keeps the instance alive when WASM code is on the stack, since the instance object is passed as a parameter and spilled onto the stack.

This is a follow-up to https://chromium-review.googlesource.com/981687. When a wasm function has a large stack frame, the x64 code generator performs the stack overflow check before constructing the frame. This requires the use of the `address_of_real_stack_limit` external reference. This reference is thread local, so if it is not relocated the stack overflow check will always fail.

The test inspects each builtin's RelocInfo. It's isolate-independent, iff there are no entries for embedded objects, runtime calls, external references (which could point to addresses on the isolate), or code targets.

This reloc mode is never encoded, so there is no reason to differentiate between 32 and 64 bit. Both are now replaced by RelocInfo::NONE.

Tag RelocInfo which belongs to native wasm code, and fix printing to not try to access the Code object for CODE_TARGET, but rather just print "(wasm trampoline)".

Remove an unused constructor and an unused field, and compute a more tight {kMaxSize}. Beside being a cleanup, this might sometimes allow us to allocate a little bit less memory on 32 bit systems.

This prints nicer error messages for checks like "DCHECK_EQ(reg1, reg2)", and also splits cache state tracing into one method for printing the overall state, one for printing each slot, and one for printing the register.

- When a dictionary mode prototype changes, invalidate the validity cell. - The dictionary mode prototypes don't need to be gathered into an array in InitPrototypeChecks.
