Browse Source 
- Declarative environment no longer need to lookup the created binding for setting it's value
- Unfold vm_decl_var and vm_set_var into vm_loop to reduce error checks
- Reduce code duplication in ecma_module_connect_imports
- Fix deleted binding setting in `ecma_op_set_mutable_binding` (fixes #4468)
