Fix crash on Return to Menu in Symbian.

Browse Source 
We don't want to free the executable code (actually a Chunk+Heap) using same method we use to free memory pages (delete).
This would be the same situation on jailbroken iOS and WP.
Now the JIT code is always allocated and never freed on Symbian.
