Since it is a float, how about using the value NaN? I think that
nicely summaries it is a useless value.
However, i agree, we first need a technical justification for needing
a value at all.
Jon: What happened when you posted a patch removing this value from
x86? That is clearly an alternative to adding it to ARM, especially if
everybody agrees it is a useless value.
