ir3: Disable copy prop for immediate ldlw offsets
Immediate offsets are currently collapsed for ldlw, but ldlw does
behave correctly with immediate values. For example,
`ldlw.u32 r0.x, l[4], 1` actually means to use the value of
regid 4 (r1.x) as the offset when we actually want it to use the
imm value of 4 as the offset.
This commit disables copy prop for ldlw offsets so the same
intrinsic gets compiled to:
mov.u32u32 r0.y, 0x00000004
ldlw.u32 r0.x, l[r0.y], 1
