Subzero: x86-64: Allow immediates in 64-bit instructions. The original code legalized *all* i64 constants into a register move, creating unnecessary instructions and slightly higher register pressure in most cases. Generally, immediates can be used in 64-bit instructions as long as the immediate can be represented as a sign-extended 32-bit value.
