Variables/return values with constexpr type cannot have multiple
assignments. We check this now.
For conditionals, it is important to always infer a non-constexpr type.
This CL adds the ability to map any type (including union types) to be
mapped to their non-constexpr variant. Conditionals infer their type as
the non-constexpr version of a combination of the two branch types.
In addition, this improves subtyping for constexpr types:
If A extends B, then constexpr A extends constexpr B.
This makes it necessary to clean up "constexpr String", which has nothing
to do with tagged values.

This CL changes the NumberDictionary fast-path for Array.p.sort to
throw a TypeError when trying to write to a read-only property.
Previously, the fast-path simply bailed to the slow-path which could
swallow the TypeError by accident. I.e. because the fast-path could
leave the array in an inconsistent state that is already sorted.
Example:
let arr = new Array(10);
Object.defineProperty(arr, 0, {value: 2, writable: false});
Object.defineProperty(arr, 2, {value: 1, writable: false});
arr.sort();
The pre-processing step will move the value 1 to index 1: {0: 2, 1: 1}
When trying to swap those 2 values, the fast-path will write the 2 at
index 1, then try to write the 1 at index 0 and fail, bailing to the
slow-path. As the array looks like {0: 2, 1: 2} its already sorted
and the TypeError will not be thrown.

For spread calls with arrays with double elements but zero length,
we skip the box-as-heapnumber step; so in this corner case the
Call builtin sees a FixedDoubleArray, which is fine because it
doesn't read any of the raw double values from it.
This patch doesn't change the implementation, it only updates the
assert to match reality.

On Windows (32-bit), we need to emit explicit stack limit checks for
stack frames bigger than one page (4kB). This CL implements this by
emitting corresponding code at the end of Liftoff functions if needed.

This correctly serializes {RelocInfo::INTERNAL_REFERENCE} addresses in a
position-independent form, so that they can be properly relocated when
the code is deserialized again. We store the offset within the code in

called on main thread) and use it to create the handle in
ConsumedPreParsedScopeData::GetDataForSkippableFunction, rather than
calling GetIsolate.
