intel/compiler: use correct swizzle for replacement
The optimization in 4cd1a0be76883c introduced a replacement of :
cmp(8).z.f0.0 vgrf11.y:D, vgrf10.xxxx:D, vgrf2.xyyy:D
...
cmp(8).nz.f0.0 null.x:D, vgrf11.yyyy:D, 0D
By :
cmp(8).z.f0.0 vgrf15.x:D, vgrf10.xxxx:D, vgrf2.yyyy:D
...
mov(8) vgrf11.y:D, vgrf15.yyyy:D
The first cmp instruction is storing in x while the second mov is
sourcing from y. We need to take into account where the replacement on
the scan_inst destination is going to store thing so that the
replacement mov can source things from the correct location.
