This fixes String::MakeExternal() to bail out if the subject string
doesn't fit a regular ExternalString, instead of creating a short
external string. The observation here is that for short external strings
the overhead of having to have the StringResource plus going to the
runtime/C++ for each and every character access from JavaScript land
is probably bigger than the anticipated benefits.
If this turns out to be wrong and there's a real benefit, we should make
use of ThinStrings instead of having a separate way to represent
external strings.

In order to test that we don't repeatedly go through the
WasmCompileLazy runtime function, add a flag to the
LazyCompilationOrchestrator to "freeze" it, i.e. disallow any further
lazy compilation.
In tests, use this flag to first call a method, then freeze lazy
compilation, then call the method again to assert that no further lazy
compilation is triggered.
This test currently fails with --wasm-jit-to-native, so disable it for
that variant.

In TurboFan we can easily recognize calls to String.prototype.slice
where the start parameter is -1 and the end parameter is either
undefined or not present. These calls either return an empty string if
the input string is empty, or the last character of the input string
as a single character string. So we can just make use of the existing
StringCharAt operator.
This reduces the overhead of the String.prototype.slice calls from
optimized code in the chai test of the web-tooling-benchmark
significantly. We observe a 2-3% improvement on the test.

Previously, the class fields initializer function was stored on a
synthetic context allocated variable. This approach had sevaral
problems:
- We didn't know that class literal had fields until after we had
completely parsed the class literal. This meant that we had to go back
and fix up the scope of the constructor to have this synthetic
variable. This resulted in mismatch between parser and preparsed scope
data.
- This synthetic variable could potentially resolve to an initializer
of an outer class.
For ex:
class X extends Object {
c = 1;
constructor() {
var t = () => {
class P extends Object {
constructor() {
var t = () => { super(); };
t();
}
}
super();
}
t();
}
}
In this the inner class P could access the outer class X's initiliazer
function. We would have to maintain extra metadata to make sure this
doesn't happen.
Instead this new approach uses a private symbol to store the
initializer function on the class constructor itself.
For the base constructor case, we can simply check for a bit on the
constructor function literal to see if we need to emit code that loads
and calls this initializer function. Therefore, we don't pay the cost
of loading this function in case there are no class fields.
For the derived constructor case, there are two possiblities:
(a) We are in a super() call directly in the derived constructor:
In this case we can do a check similar to the base constructor check,
we can check for a bit on the derived constructor and emit code for
loading and calling the initializer function.
This is usually the common case and we don't pay any cost for not using
class fields.
(b) We are in a super() call inside an arrow function in the derived
constructor:
In this case, we /always/ emit code to load and call the initializer
function. If the function doesn't exist then we have undefined and we
don't call anything. Otherwise we call the function.
super() can't be called twice so even if we emit code to load and call
the initializer function multiple times, it doesn't matter because it
would have already been an error.

The existing access to the signatures is plain wrong. This CL fixes
this.
Note that cross-instance indirect calls are only enabled since a few
days (https://crrev.com/c/778159), which is why this bug was not
detected before.

The tsan skips were getting a bit spread all over the place. Added a
section for them below msan and asan to keep things together, where
the only cause for skipping the test is tsan.
