The DCHECK verified capacity just before the call to EnsureCapacity()
(which extends capacity if needed). This DCHECK can just be removed
since FixedArray::set() already checks the given index is in-bounds.
Drive-by: Remove similar duplicate DCHECKs in FixedArrayBuilder.

> [builtins]: Optimize CreateTypedArray to use element size log 2 for calculations.
>
> TypedArrayElementsInfo now represents an element's size as a log 2 and typed as
> uintptr. This simplifies and speeds up (avoids possible HeapNumber allocations) a
> number of calculations:
>
> - Number of Elements (length) -> Byte Length - is now a WordShl
> - Byte Length -> Number of Elements (length) - is now a WordShr
> - Testing alignment (byte offset or length) - is now a WordAnd
>
> These element/byte length related calculations are encapsulated in
> TypedArrayElementsInfo as struct methods.
>
> This reduces the size of CreateTypedArray by 2.125 KB (24%) on Mac x64.release:
> - Before: 9,088

We'll let the bytecode compiler and optimizing compilers deal with dead code,
rather than the ast visitors. The problem is that the visitors previously
disagreed upon what was dead. That's bad if necessary visitors omit parts of
the code that the bytecode generator will actually visit.
I did consider removing the AST nodes immediately in the parser, but that
adds overhead and actually broke code coverage. Since dead code shouldn't be
shipped to the browser anyway (and we can still omit it later in the bytecode
generator), I opted for keeping the nodes instead.

(2) Rename the name of the backing store of WasmTables from `functions`
to `elements`.
- The name `functions` just does not fit anyref tables.
(3) Generate code with TurboFan for table.get and table.set.
(4) Extend wasm-module-builder.js to be able to generate modules with

That way we can properly walk the active ambiguous stack of expressions and
stop where it's non-ambiguous. In the bug we would have forced context
allocation of "this" in an outer function because an inner function was parsed
as part of an arrow function head and "this" was referenced. That caused the
ambiguous arrow head scope to be marked, even though the reference came from a
non-ambiguous function.

We often use raw assertPromiseResult with {success ==
assertUnreachable} for that. Having a separate helper increases
readability and allows us to generate consistent (and better) error
messages.

This adds constant field tracking for arrays. To prevent changing the
field in some other elements-kind-branch of transition tree, we only
use the const information in the optimizing compiler if the map is not
an array map or if the map is stable (since stable maps cannot
transition to a different elements-kind-branch without deopt).
