Description Alexey Shvayka 2023-08-21 13:23:56 PDT 
Related test262 failures:
  * test/language/statements/switch/scope-lex-async-function.js
  * test/language/statements/switch/scope-lex-async-generator.js
  * test/language/statements/switch/scope-lex-generator.js

Fix: add template parameter to `std::pair<DeclarationResultMask, ScopeRef> declareFunction(const Identifier*)` of Parser.h to avoid hoisting function unconditionally.
