> ### 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
