Egel interpreter runs twice as fast in VM

 Okay, so I ported the interpreter to Fedora 34 (arm64) in a virtual machine on the Air. Now the microbenchmark runs twice as fast than on native, 2.5 seconds.

I thought I might have messed up and the thing doesn't garbage collect, so tested that and:

So that isn't it. Maybe the VM thinks it's a uniprocessor.
