* Fix rest parameters indexing with TypeScript 'this parameter'

The TypeScript [this parameter][0] is a fake parameter and should not be
taken into account when counting the function parameters.  This patch
skips it by using the condition taken from the `transform-typescript`
plugin.

Note: since the `transform-typescript` plugin is removing this kind of
parameter, including it before the `transform-parameters` plugin solves
the issue.  This patch fixes the issue in other cases.

[0]: https://www.typescriptlang.org/docs/handbook/functions.html#this-parameters

* nit: improve the 'this parameter' detection condition

* improve performance by checking the parameter list length before
accessing it
* simplify the test a bit by using the `isIdentifier` second
parameter

Fixes issue 10989 where the only the identifier in a member expression that is the value of an object property would be parsed. Removing checkExpressionErrors in parseExprSubscripts results in the subscript also being parsed.

… support (#11268)

* Allow rest/spread on polyfilled or builtin iterables when `Symbol` unsupported

Currently, when `Symbol` is not supported, we allow using rest/spread with:
- arrays
- strings
- arguments

With this PR, it will be also possible to use it with
- maps
- sets
- binary arrays

While in old browsers es6 builtins would still need to be polyfilled, it's way
easier to polyfill them because `Symbol` cannot be reliably polyfilled.

I didn't use `instanceof` becase:
- it doesn't work with polyfills not attatched to the global scope
- when using Babel to load polyfills, it would force the inclusion of `Map` and `Set` polyfills even if they are not used

Downside: the current approach of relying on `toString || construcor.name` doesn't work with subclasses.
