[GlobalIsel] Add combine for select with constants (#121088)
The SelectionDAG Isel supports the both version of combines mentioned
below :
```
select Cond, Pow2, 0 --> (zext Cond)  << log2(Pow2) 
select Cond, 0, Pow2 --> (zext !Cond) << log2(Pow2)
```
The GlobalIsel for now only supports the first one defined in it's
generic combinerHelper.cpp. This patch adds the missing second one.
