Bjorn Pettersson 8f041837f3 [SelectionDAG] Fix miscompile bug in expandFunnelShift 
This is a fixup of commit 0819a6416fd217 (D77152) which could
result in miscompiles. The miscompile could only happen for targets
where isOperationLegalOrCustom could return different values for
FSHL and FSHR.

The commit mentioned above added logic in expandFunnelShift to
convert between FSHL and FSHR by swapping direction of the
funnel shift. However, that transform is only legal if we know
that the shift count (modulo bitwidth) isn't zero.

Basically, since fshr(-1,0,0)==0 and fshl(-1,0,0)==-1 then doing a
rewrite such as fshr(X,Y,Z) => fshl(X,Y,0-Z) would be incorrect if
Z modulo bitwidth, could be zero.

```
$ ./alive-tv /tmp/test.ll

----------------------------------------
define i32 @src(i32 %x, i32 %y, i32 %z) {
%0:
  %t0 = fshl i32 %x, i32 %y, i32 %z
  ret i32 %t0
}
=>
define i32 @tgt(i32 %x, i32 %y, i32 %z) {
%0:
  %t0 = sub i32 32, %z
  %t1 = fshr i32 %x, i32 %y, i32 %t0
  ret i32 %t1
}
Transformation doesn't verify!
ERROR: Value mismatch

Example:
i32 %x = #x00000000 (0)
i32 %y = #x00000400 (1024)
i32 %z = #x00000000 (0)

Source:
i32 %t0 = #x00000000 (0)

Target:
i32 %t0 = #x00000020 (32)
i32 %t1 = #x00000400 (1024)
Source value: #x00000000 (0)
Target value: #x00000400 (1024)
```

It could be possible to add back the transform, given that logic
is added to check that (Z % BW) can't be zero. Since there were
no test cases proving that such a transform actually would be useful
I decided to simply remove the faulty code in this patch.
