Describe the bug

There are some broken test cases in the Esprima test suite:

False negatives (cases that produce an error while they shouldn't):

• ES6/identifier/invalid_expression_await.module.js
• expression/primary/literal/regular-expression/migrated_0006.source.js

False positive (cases that don't produce an error while they should):

• es2017/async/functions/async-if.js
• es2017/async/functions/async-if-await.js
• ES6/binding-pattern/array-pattern/for-let-let.js
• ES6/binding-pattern/object-pattern/for-let-let.js
• ES6/export-declaration/export-named-keyword-as-specifier.js
• ES6/export-declaration/export-named-keyword-specifier.js
• ES6/identifier/module_await.js (illegal since ES2022)
• ES6/template-literals/escape-sequences.source.js (see the result of eval('(s => s.raw[0])`\\n\\r\\b\\v\\t\\f\\\n\\\r\n`'))
• ES6/template-literals/line-terminators.source.js (\r\n is normalized to \n in raw strings as well)
• ES6/yield/yield-generator-arrow-default.js
• ES6/yield/yield-generator-default-parameter.js
• statement/iteration/unterminated-do-while.json
• statement/with/unterminated-with.js
