* `Context` independent `CodeBlock`s
This allows us to share `CodeBlock`s between `Context`, which makes
functions sharable between `Context`s.
* Apply review
* Move `FunctionKind` flag to CodeBlock
* Add `IS_ARROW` flag to codeblock
* Remove GetAsyncArrowFunction and GetFunctionAsync opcodes
* Remove GetGeneratorAsync opcode
* Refactor `Context::run()` method
- Remove async generator close from run
- Remove promise capability from run
- Remove promise capability check from call_internal
- Remove generator creation from call_internal
- Move promise capability creation to separate opcode
* Inline ReThrow opcode in run
* Refactor environment, exception handling, generators and jumping in VM
* Add helper for JumpIfNotResumeKind opcode
* Better handler display for CodeBlock
* Update documentaion
* Factor exception handling from throw opcodes
* Simplify try compilation
* Only push try statement jump controll info if needed
* Add helper functions checks in async and generator
* Run prettier
* Remove redundant check for end of bytecode.
We always emit a `Return` opcode at the end of a function, so this should never be reached.
* Fix doc link
* Implement stack_count calculation of handlers
* Fix typo
* Rename `LoopContinue` to `IncrementLoopIteration`
* Fix typo
* Remove #[allow(unused)] from Handler field
* Move `RefCell` of `CompileTimeEnvironment`s to field `bindings`
All field except the `bindings` field are mutated after `CompileTimeEnvironment`
creation. It moves the `RefCell` to `bindings` field, this cleans the methods callsites.
* cargo-clippy
* Close active iterators when returning from async generator
* Fix remaining async generator tests
* Fix remaining async generator tests
* Replace some reserved opcodes
* Fix for await of loop flag
* Add tests for fix
* Remove whitespace
* Fix test display and improve test
* Change `usize` to `u32`
* Remove redundant `num_bindings` field from `CodeBlock`
* Remove redundant num_bindings parameter from push_function_inherits
* Remove redundant num_bindings operand from environment opcodes
* Make pop_compile_environment() return an index
* Move boolean `CodeBlock` flags to bitflags
* Fix ci
* Add doc
