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.

This CL contains the following changes:
(1) Allocate memory for WasmTables in the WasmInstance.
- We extend the WasmInstance by a FixedArray which stores
references to the WasmTables.
(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
multiple tables.
(5) Add mjsunit tests to test table.get and table.set.

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.

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).

The result of Object::ToInteger is a number rounded to an
integer value, but not necessarily in the range of what a
C++ "int" can represent. Doing the 2 <= radix <= 36 range
check first makes the subsequent cast safe.

This adds support for integrity level transitions (preventExtensions,
seal and freeze) to MapUpdater and Map::TryUpdate.
In both cases, we first try to detect whether there were integrity
level transitions in the transition tree to the old map and make note
of the most restrictive integrity transition and the map just before
the transition (integrity-source-map). Then we find an appropriate root
(based on integrity-source-map's elements kind) and replay the
transitions based on the integrity-source-map's descriptor
array. Finally, if we saw an integrity level transition in
the beginning, we will find-or-create that transition (on the
updated version of integrity-source-map).
For the following micro-benchmark, we get about 10x speedup.
```
function C() {
this.x = 1;
Object.seal(this);
this.x = 0.1;
}
const start = Date.now();
for (let i = 0; i < 1e7; i++) {
new C();
}
console.log("Reconfigure sealed: " + (Date.now() - start));
```

This CL replaces the current TypedArray#sort with a simpler mergesort.
The fastpath when the user does not provide a comparison function
is still used.
In addition, TypedArray#sort now converts all elements in the
TypedArray to tagged values upfront, sorts them and writes them
back into the TypedArray as the final step.

Changes made to the Wasm module builder:
- Create emit_u64v for emitting a LEB128 that conceptually represent
an 64-bits integer.
- Differentiate toBuffer and toUint8Array for returning respectively
ArrayBuffer and a Uint8Array.
- Moved wasmF32Const and wasmF64Const functions because we can take
advantage of the existing cached conversion buffers. Also, declaring
them in the constants file will collide with the module-builder since
they are loaded in the same scope.
- The byte_view buffer (used by some conversions to bytes) switched from
Int8Array to Uint8Array.
Changes made to the Wasm contants:
- Add a new kSharedHasMaximumFlag flag for shared memory with a maximum
value.
