[arm-allstar] someone did made it on the rpi3

[David Lang]

amd64 vs x86 is a rare situation where the 64 bit modes are a huge win because 
the design is register starved and 64 bit doubles the number of registers. In 
most other architectures, 64 bit mode only changes the size of the math that you 
can do (and the memory you can access), so it's only a win on big memory or math 
heavy apps. 64 bit mode does make the programs larger, sometimes significantly 
so.

Since the Pi3 only has 1G of ram, the memory doesn't drive 64 bit mode, and I 
doubt that the 64 bit math will help enough to overcome the memory footprint 
penalty, but we'll have to see.

I don't think the ARM 64 bit mode has anything else that would make it better 
than 32 bit mode.
