[qfcc] Add failing test for vector constant init

Browse source 
Raw 'x y z' style vector constants that look like ints (no fractional
parts) used to initialize vector globals/constants don't get converted
to float vectors, resulting in nans for negative values and denormals
for positive values. This tends to make game physics... interesting.
