Based on @phire's idea, Inline constants are constants that can be used as imms in instructions. This - Adds OP_INLINECONSTANT to represent them in the IR - Modifies the ConstProp pass to transform OP_CONSTANT to OP_INLINECONSTANT based on per-platform heuristics - Modifies the backends to use imms - Supported opcodes: Add, Sub, Lsl, Lsr, Asr, Ror, Rol
