slp: Fix handling of IFN_CLZ/CTZ [PR112536]
We ICE on the following testcase now that IFN_C[LT]Z calls can have one or
two arguments (where 2 mean it is well defined at zero).
The following patch makes us create child node only for the first argument
and compatible_calls_p ensures the other argument is the same, which
at least according to the testcase seems sufficient because of vect
patterns.
