Loo Rong Jie e77ae92738 Fix print-bytecode in release build without setting OBJECT_PRINT 
Before this, --print-bytecode flag was available in all Release builds
but did not actually print the bytecodes because OBJECT_PRINT is not set.

The output was pretty confusing:

[generating bytecode for function: ]
000002115442ABE9 <BytecodeArray[27]>[generating bytecode for function: main]
000002115442B069 <BytecodeArray[114]>[generating bytecode for function: Primes]
000002115442B729 <BytecodeArray[63]>[generating bytecode for function: Int32Array]
000002115442BB51 <BytecodeArray[175]>[generating bytecode for function: Primes.getPrimeCount]
000002115442BE81 <BytecodeArray[7]>[generating bytecode for function: Primes.isPrimeDivisible]
000002115442BFC9 <BytecodeArray[71]>[generating bytecode for function: Primes.addPrime]
000002115442C1C1 <BytecodeArray[31]>[generating bytecode for function: Primes.getPrime]
000002115442D7B1 <BytecodeArray[14]>

With this CL, --print-bytecode flag will always output bytecode, but
detailed info about constant pool and handler table are still guarded.

Bug:NO
