`llvm-mca` relies on the predicates to be based on `MCSchedPredicate` in order to resolve the scheduling for variant instructions. Otherwise, it aborts the building of the instruction model early. However, the scheduling model emitter in `TableGen` gives up too soon, unless all processors use only such predicates. In order to allow more processors to be used with `llvm-mca`, this patch emits scheduling transitions if any processor uses these predicates. The transition emitted for the processors using legacy predicates is the one specified with `NoSchedPred`, which is based on `MCSchedPredicate`. Preferably, `llvm-mca` should instead assume a reasonable default when a variant transition is not based on `MCSchedPredicate` for a given processor. This issue should be revisited in the future.
