Yukihiro "Matz" Matsumoto e84f7bb3b0 mruby-compiler: remove unnecessary MOVE/APOST in simple masgn ...

For simple parallel assignment like `a,b = 1,2` without rest or post
variables, skip generating APOST instruction and unnecessary MOVE.
The values are already extracted via AREF.

Before (27 bytes):
    LOADI_1 R3
    LOADI_2 R4
    ARRAY   R3 2
    AREF    R1 R3 0
    AREF    R2 R3 1
    MOVE    R4 R3
    APOST   R4 2 0
    MOVE    R4 R3
    RETURN  R3

After (18 bytes):
    LOADI_1 R3
    LOADI_2 R4
    ARRAY   R3 2
    AREF    R1 R3 0
    AREF    R2 R3 1
    RETURN  R3
