arch: Make the generic micropc enabled PCState set nupc to 1.
The default constructor of the micropc enabled generic PCState class
set the next micropc to 0, when the non-default constructor and at
least the x86 initCPU utility function set it to 1. This makes more
sense since either the micropc doesn't matter as a concept if the
instruction isn't microcoded, or, unless redirected by a micropc
branch, you're going to want to execute the next microop and not just
repeat the first one.
