This is a reland of commit 80fb2815

This CL fixes the signedness of rematerialized Numbers from immediates, which was introduced by the original change. Besides, BigInt truncation to zero bits is lowered to Int64Constant instead of NumberConstant of zero, which will flow into the state values directly.

Original change's description:
> [turbofan] Rematerialize BigInt64 in deopt
>
> This CL introduces two MachineTypes - SignedBigInt64 and UnsignedBigInt64, which are represented as Word64 but will be rematerialized to BigInt in deoptimization. This will avoid unnecessary conversions for BigInt64s when they are passed to StateValues.

V8-side implementation for trusted types fromLiteral.

Create a separate JSArray root map for template literal objects to
clearly identify untampered template literals belonging to a given
context.

Given that template literals are frozen arrays with a 'raw' property,
we don't expect additional polymorphism.

Drive-by-fix:
Avoid ValidateElements call in NewJSArrayWithElements.

We set the JSArray's length to the elements's length before,
which is wrong when the elements have the slack part. We could
serialize the correct length and only the actual elements excluding
the slack part for JSArray's elements. And we do the same thing
for the objects to avoid serializing unnecessary elements.
