Fix printing edge cases in Nullish Coalescing and Optional Ch… (#11255)
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 {}`

da0af5fd99 V8intrinsic syntax plugin (#10148)
* feat: v8intrinsic syntax plugin

Implement V8 Intrinsic Syntax Extension. Here we check the execution branch inside the parseSubscript to make sure the V8IntrinsicIdentifier is immediately followed by a call expression.

* feat: disable combining placeholders and v8intrisic

per https://github.com/babel/babel/issues/10104#issuecomment-506950969

* test: add more error cases

* refactor: parse v8 intrinsic in parseExprAtom

This approach is identical to V8’s implementation. Move the test cases as the behaviour changes.

* fix: plugin-name typo

* test: add yield-expression test case

* feat: require startsExpr on modulo for v8intrinsic

* perf: skip eof and braceR check as they must return false

* Print V8IntrinsicIdentifier

* feat: add v8intrinsic to parser typings

* Add generated type helpers

* fix: incorrect type definition

* fix: allow V8IntrinsicIdentifier to be callee
