Add FogParam0::FloatValue and FogParam3::FloatValue
...
This value will be used in the register description; so expose it in a way that can be re-used instead of calculating it in 2 places later.

BPMemory: Handle fog configuration where both A and C are infinity/NaN
...
The console appears to behave against standard IEEE754 specification
here, in particular around how NaNs are handled. NaNs appear to have no
effect on the result, and are treated the same as positive or negative
infinity, based on the sign bit.
However, when the result would be NaN (inf - inf, or (-inf) - (-inf)),
this results in a completely fogged color, or unfogged color
respectively. We handle this by returning a constant zero for the A
varaible, and positive or negative infinity for C depending on the sign
bits of the A and C registers. This ensures that no NaN value is passed
to the GPU in the first place, and that the result of the fog
calculation cannot be NaN.
