[SimpleLoopUnswitch] Increment stats counter for unswitching switch instruction

Browse Source 
Increment statistics counter NumSwitches at unswitchNontrivialInvariants() for
unswitching a non-trivial switch instruction. This is to fix a bug that it
increments NumBranches even for the case of switch instruction.
There is no functional change in this patch.
