Fix super calls so that arguments are evaluated before the
super constructor is checked to be in fact a constructor.
A new bytecode is introduced to split the IsConstructor check
out from the current GetSuperConstructor bytecode.

Implements https://github.com/tc39/ecma262/pull/2154, which allows
module export names to be string literals.
Semantics highlights:
- It is a SyntaxError for string literal export names to have unpaired
UTF16 surrogates.
- It is a SyntaxError for string literal export names to be used as
the local name without being followed by a 'from' clause. For example,
`export { "foo" }` and `export { "foo" as "bar" }` are errors, but
`export { "foo" } from "./module.js"` is allowed.
The remaining failing test262 test is wrong:

https://github.com/tc39/ecma262/pull/1776 is a normative change that
reached consensus in the November 2019 TC39. It changes
%AsyncFromSyncIteratorPrototype% methods to forward the absence of
arguments to the underlying sync iterator. This is observable via
`arguments.length` inside the underlying sync iterator.
For example, .next is changed to, roughly:
```
%AsyncFromSyncIteratorPrototype%.next = function(value) {
let res;
if (arguments.length < 1) {
res = [[SyncIteratorRecord]].[[Iterator]].next();
} else {
res = [[SyncIteratorRecord]].[[Iterator]].next(value);
}
// ...
};
```
