i965: Don't change F->VF if dest type is DF.

Browse source 
We change the immediate source type to VF to allow instruction
compaction, but there are no entires in the compaction table for DF, so
there's no point in doing this.

Additionally, I mixing floating-point types is now allowed except for
F and VF.
