[Soft-Float] - Fixes Tony Hawk Pro Skater 4 Mul issue. 

The game sends some super low floats to the Mul unit.

On PS2, floats with exponent zero should return zero, but this is not the case in Mul, the multiplier can work with denormals internally.

I love when undocumented stuff is used by some games for their 3D engine ^^.
