/*
This may look like a fakematch, however this actually makes sense if you break it down:
1) Shift right to clear bottom 2 nybbles;
2) Shift left to put the moved nybbles back to their original location
3) Mask off the top nybble leaving only 3rd nybble
So taking 0x1234567 as an example the logic looks something like this
1) 0x12345678 >> 16 == 0x00001234
2) 0x00001234 << 16 == 0x12340000
3) 0x12340000 & 0x00FFFFFF == 0x00340000
This behavior could also be matched with a simple mask
0x12345678 & 0x00FF0000 == 0x00340000
But on PPC with CodeWarrior this just produces an improper load:
`
lwz r0,0(r29)
rlwinm r0,r0,0,8,0xf
`
Instead of the expected
`
lwz r3,0(r29)
rlwinm r0,r3,0,8,0xf
`
Note the use of r3 instead of r0
