Juergen Ributzka 8841fb5f25 [FastISel][AArch64] Fix a few BuildMI callsites where the result register was added as an operand register.
This fixes a few BuildMI callsites where the result register was added by
using addReg, which is per default a use and therefore an operand register.

Also use the zero register as result register when emitting a compare
instruction (SUBS with unused result register).
