LibJS/Bytecode: Don't begin breakable scope before variable scope in for

This is no longer required, since the variable scope is ended after
switching to the end block, which means that LeaveLexicalEnvironment
will always be generated instead of depending on the unwind mechanism
to handle it for us.
