[gamecode] Clean up the conversion instructions
Float bit-ops as well. Also, add q*v4 and v4*q instructions. There are currently 48 free opcodes, and I might remove the scale instructions, but they could be useful as expanding a single float to a vector would take 3 instructions (copy to temp, swizzle-expand temp, multiply, vs just scale).
