* 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.
* Don't use Array.from for array-like objects
* Add stricter Optional Chain node validation
Optional chains cannot start with `optional: false`. Somewhere in the `object`/`callee` tree, there must be an optional with `optional: true`.
* Print current node's type when finding an error.
* Extract for-of iterator handling to a helper
Dis greatly recudes the code size when for-of is used multiple times across the
codebase. Also, makes it easier to read what's happening in a compiled loop.

* Added support for record and tuple syntax.
This commit adds support for both the hash #{} and bar {||}
syntaxes to babel-parser, as well as adds the supporting
babel-plugin-syntax-record-and-tuple plugin to enable support
for the syntax. Does not include any transform for records and
tuples.
* typo
* added check to ensure recordAndTuple in babel-parser
* switched to syntaxType option instead of explicit entries for each record and tuple type
* switched to using recordAndTupleSyntaxType for generator options instead of adding to node
* added tests for generator option recordAndTupleSyntaxType
* added test for record and tuple bar syntax with flow typings
* added tests for invalid/missing recordAndTuple syntaxType parser option
* fixed flowcheck errors
* fix merge with class privates in tokenizer
* Update packages/babel-parser/src/types.js

* Update Purish aliases
- Adds `Purish` to `RegexLiteral`, since it can't cause any side-effects.
- Removes `Purish` from `ClassExpression` and `ClassDeclaration`, since they can be impure with static class fields.
* Update types
This is a mix of changes, most importantly:
- Always print parens when mixing nullish coalescing and another logical
- Fixes assignment in the callee of an optional chain, which now blocks #11248
Also, cleans up a bit of code, and removes an unnecessary parens around `class A extends new B {}`
* Use ~ for preset-env's @babel/compat-data dependency
* Revert "Use ~ for preset-env's @babel/compat-data dependency"
This reverts commit e7d57c7894095d381670cddfbbce06bd2a480a32.
* Allow using `preset-env` with newer versions of `compat-data`
