Not much to do here. This CL bakes in incompatibility between poisoning and embedded builtins, since we cannot unconditionally reset the poison register (which we reused as kRootRegister) as we used to. It also exposes a bug introduced in [0] where we set Isolate::c_function to a garbage value.

This also adds checks that ebx contains the root pointer during indirect load. And we work around a few spots where we create an ebx Register but do not actually reference it (e.g. when emitting xmm3, which has the same code as ebx).

Currently, wasm memory and wasm code use a shared limit for the total size of reservations. This can cause wasm code reservations to fail because wasm memories used all available reservation space. This CL introduces a soft limit which is used when allocating wasm memory with full guards. If this limit is reached and the respective flag is set, we fall back to allocation without full guards and check against the hard limit. Code reservations always check against the hard limit.

Teach TurboFan about representation changes from Float64 to Word64 where the input value is already known to be within the Int64 or Uint64 range. While not all of these values have representations in Float64, those that do can be converted to Word64 without loss of precision. Same is true for Tagged to Word64 conversions, although here we don't (currently) need the case for Uint64 ranges, so we can skip adding an operator for that until it becomes necessary (there's a hard check in the code so it'll not silently cause trouble).

The JSTypedArray instance is created early on in the TypedArray constructors, using EmitFastNewObject, which puts Undefined into all slots. But the code might still produce an exception afterwards leaving the JSTypedArray in a weird state. It's not a security issue since the object doesn't escape, but it confuses the heap verifier.

This is the next step to support large array buffers. On 64-bit archs the full safe integer range is available (up to 2^53-1 bytes in theory). On 32-bit platforms the full Unsigned31 range is allowed, so that we can continue to use CheckBounds for typed arrays and data views in the optimizing compiler (it's generally unlikely that the kernel will give you more than 1GiB of contiguous memory anyways). Drive-by-fix: This introduces proper chokepoints for the byte_offset and byte_length accesses in the CSA code, and also does some renaming for consistency.

For 64-bit indices it's not safe to pass Truncation::Word32() for indices, as operations will incorrectly truncate the outputs to 32-bit integers. There's also not really a point in not passing Truncation::Any(), but it might have performance impact (since we misuse IsUsedAsWord32 in various places).
