This requires Data Flow Analysis, which slows the compiler down. It's not a good 
idea to have the semantics change when turning the optimizer on.

Note that when the optimizer is run on D code, any redundant NaN initialization 
gets removed, so there is no penalty for default initialization. (It's called 
"Dead Assignment Removal".)
