ASSERTION FAILED: The bit sizes of src and the dst is not identical on Haswell GT2 Mobile

Repro

typedef struct __attribute__ ((packed)) {
    uint a;
    uint b;
    uint c;
} s;

kernel void k(__global const s* ins, __global uint* out) {
  uint a = ins[0].a;
  uint b = ins[0].b;
  uint c = ins[0].c;
  out[0] = a;
  out[1] = b;
  out[2] = c;
}

Gives the following sequence

  %0 = bitcast %struct.s addrspace(1)* %ins to <3 x i32> addrspace(1)*
  %1 = load <3 x i32>, <3 x i32> addrspace(1)* %0, align 1
  %2 = extractelement <3 x i32> %1, i32 0
  %3 = extractelement <3 x i32> %1, i32 1
  %4 = extractelement <3 x i32> %1, i32 2
  %5 = bitcast i32 addrspace(1)* %out to <3 x i32> addrspace(1)*
  %6 = insertelement <3 x i32> undef, i32 %2, i32 0
  %7 = insertelement <3 x i32> %6, i32 %3, i32 1
  %8 = insertelement <3 x i32> %7, i32 %4, i32 2
  store <3 x i32> %8, <3 x i32> addrspace(1)* %5, align 4
  ret void
