Matt Arsenault 4b28ee2088 MemCpyOptimizer: Use max legal int size instead of pointer size ...

If there are no legal integers, assume 1 byte.

This makes more sense than using the pointer size as
a guess for the maximum GPR width.

It is conceivable to want to use some 64-bit pointers
on a target where 64-bit integers aren't legal.
