[qfcc] Allow some mixing of vector/quaternion types

Browse source 
That is, vector ops with 3-component general vectors and quaternion ops
with 3 and 4 component general vectors "promote" the general vectors to
vector or quaternion as appropriate. Needed for operations with
vector and quaternion literals.
