This change fixes the handling of lexical blocks when executing multiple scripts, and also fixes a few issues with module environments. After this change, all script files will run in the same context and will have access to lexically scoped global variables of previous scripts, and module environments will no longer have a bound global 'this' value. The REPL implementation in main-unix is also fixed to correctly handle lexically scoped variables. Fixes #3561. JerryScript-DCO-1.0-Signed-off-by: Dániel Bátyai dbatyai@inf.u-szeged.hu
