First step to fix issue #3568. Changes: - Implemented Math.clz32(), Math.fround(), Math.imul(), Math.hypot(). - Implemented all remaining Math functions with calling the standard libm functions, but they throw UNIMPLEMENTED exception with jerry-libm, because the necessary fdlibm functions are missing and should be ported. All Math related test262 tests pass (except function name and length tests) JerryScript-DCO-1.0-Signed-off-by: Csaba Osztrogonác oszi@inf.u-szeged.hu
