PR for Promise.any: https://github.com/tc39/proposal-promise-any/pull/65
This CL includes the following cleanup changes:
- Made it more explicit that the constructor is a Constructor.
- Removed unnecessary nested try blocks (a try can have both a catch and a label).
- Moved commonly used definitions out of promise-race.tq where they don't belong.
- Made the parameter order of PerformPromiseAll match the spec.

There's no reason for it to be a JSArray; it's an internal data member.
We only have a slow version for constructing a FixedArray from an
Iterable, but since this is not a performance critical code path,
it's fine.

When an empty class is nested inside a class with private instance
methods, like this:
class Outer {
constructor() {}
#method() {}
factory() {
class Inner {
constructor() { }
}
return Inner;
}
run(obj) {
obj.#method();
}
}
The bytecode generator previously generate private brand
initialization for the constructor of Inner by mistake,
because during scope chain serialization/deserialization,
the outer scopes of Inner and factory() are not allocated
or serialized (as they are empty). In the eyes of the bytecode
generator, it then appeared as if Outer is the direct outer
scope of Inner's constructor.
In order to work around this information loss, in this patch
we rely on SharedFunctionInfo instead of the Context/ScopeInfo
chain to maintain the information about private brand initialization.
This is done by shrinking expected_nof_properties to 8 bits and
freeing 8 bits for a second bitfield on the SFI.
