Ah, I remember now where I got stuck on this before. I need to obtain this
property on the `ARMSubtarget` rather than the `ARMBaseTargetMachine`, but
neither of them expose `Options` publicly, and `ARMSubtarget` just invokes
`isTargetHardFloat` on its `TM` member, without accounting for its own
`Options`, even though they are copied from the `ARMBaseTargetMachine` when the
subtarget is created.
