[#216] Catching all annotation mismatch errors when typechecking

Description

Problem: Currently, only some instructions in typeCheckInstr do proper annotation matching (COMPARE, GET, MEM ..). A few other instructions do not throw annotation mismatch error at all, mainly arithmetic instructions (ADD, MUL, EDIV, ...).

Solution: Ensure catching all annotation mismatch errors when typechecking arithmetic instructions (ADD, MUL, EDIV, ...).
