This patch implements the core part of let/const statements. Redeclarations are correctly detected and separate contexts are correctly created for these statements. Register optimizations are also emplyed whenever possible. Lots of features are still missing: - checking the var statements in eval - const are treated as lets - single statement checks are missing - export declarations are exported as vars, let/const export is not supported JerryScript-DCO-1.0-Signed-off-by: Zoltan Herczeg zherczeg.u-szeged@partner.samsung.com
