target/alpha: Explicitly set 2-NaN propagation rule
Set the NaN propagation rule explicitly for the float_status word
used in this target.
This is a no-behaviour-change commit, so we retain the existing
behaviour of x87-style pick-largest-significand NaN propagation.
This is however not the architecturally correct handling, so we leave
a TODO note to that effect.
We also leave a TODO note pointing out that all this code in the cpu
initfn (including the existing setting up of env->flags and the FPCR)
should be in a currently non-existent CPU reset function.
