At least in the GC code we sometimes spell out the template parameter name with 
CamelCase: Iterator, Function, ClosureType, OopClosureT, Parallel, ...

I'm OK with using MT as the template parameter name. I'm also OK with using 
mem_tag, but you might hit problems when classes both have template parameter 
name and functions that take a MemTag. I see that GrowableArrayCHeap has this 
situation, but it looks like that is accidental code and isn't really needed, 
so maybe this isn't a big concern.
