Andrea Di Biagio 1885077d4c [Tablegen][PredicateExpander] Fix a bug in expandCheckImmOperand.
Function `expandCheckImmOperand` should always check if the input machine
instruction is passed by reference before calling method `getOperand()` on it.

Found while working on a patch that relies on `expandCheckImmOperand` to expand
a scheduling predicate.
