[qfcc] Support dot product for all (float) vector types

Browse source 
While the code would handle int vector types, there aren't any such
instructions, and the expression code shouldn't generate them, but all
float (32 and 64 bit) vector types do have a dot product instruction, so
check width rather than just vector/quaternion.
