### Description
The UseMallocOnly development option was originally used to detect memory stomping bugs with Arena allocations when the JVM was first in development.
The option has had a few bugs and is not in general use. There are ideas to add another way of Arena canary checking.
### Patch:
All occurrences of UseMallocOnly are removed.
### Tests:
Local, gTests: resourceArea and Arena
Mach5: tier1-5
