cpu,opcodes,gas: use %r0 and %r6 instead of %a and %ctf in eBPF disassembler

This patch changes the eBPF CPU description to prefer the register
names %r0 and %r6 instead of %a and %ctx when disassembling.  This
matches better with the current practice, vs. cBPF.

It also updates the GAS tests in order to reflect this change.
Tested in a x86_64 host.
