reduced llvm-stress test case
This small program crashes with list-ilp scheduler.
It seems that
unsigned RCId = TLI->getRepRegClassFor(VT)->getID();
doesn't work, when VT is MVT::Untyped, because getRepRegClassFor(MVT::Untyped)
returns nullptr.
Does Untyped signify an error, or is there supposed to be a regclass for this
type?
