No memory information with JERRY_FLAG_MEM_STATS

[seanshpark]

There used to be heap usage report when JERRY_FLAG_MEM_STATS was given.
Current code seems does not show them. Is it accidentally removed or intended?

I think we need to turn off JERRY_DISABLE_HEAVY_DEBUG to see it.

After commit jerryscript-project/iotjs@5f74d08 ReleaseJerry is not called before process exit, so process exits without calling jerry_cleanup, and memory statistics are not printed.
Before the commit heap usage report is printed.

[ILyoan]

I'll fix the exit before cleanup problem. Let's see if stats are printed out properly after land the patch.

@ruben-ayrapetyan , thank you!

As this question is solved and reason is not of JerryScript, I'll close this issue.
