Use one intrinsic for all sorts of interpolation. Use two separate unexpanded instructions to represent INTERP_XY and _ZW - this will allow to eliminate one part if it's not used. Track liveness of special interpolation regs instead of reserving them - this will allow to reuse those regs, lowering reg pressure.
