the option `--pre-RA-sched` with value `vliw-td` will trigger a crash.
Problem may exist in `VLIW scheduler`(selected by `vliw-td`) since other candidate schedulers (values) work fine.
Crash has be reproduced in `llvm-18.1.2`, `llvm-16` and `llvm-14`.
Reproduced with:
`/mnt/llvm-project-llvmorg-18.1.2/build/bin/llc --pre-RA-sched=vliw-td /mnt/data/acpi_listen.bc -o /mnt/data/acpi_listen.s`
trace:
```s
llc: /mnt/llvm-project-llvmorg-18.1.2/llvm/lib/CodeGen/SelectionDAG/ResourcePriorityQueue.cpp:52: llvm::ResourcePriorityQueue::ResourcePriorityQueue(llvm::SelectionDAGISel*): Assertion `ResourcesModel && "Unimplemented CreateTargetScheduleState."' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
