That's correct

No, these instructions have been removed because they are no longer in the
proposal and there is not a great set of opcodes to assign them to. These test
functions are still here to test that the compiler doesn't crash, but their
contents aren't important to test here. The instructions get scalarized and our
normal complicated lowering of fp-to-int gets applied, so we end up with a very
large amount of code in this case.

These LLVM intrinsics are no longer supported, so the entire function is
removed.
