This needs what I hope will be an easy rebase; cranelift/codegen/src/machinst/abi_impl.rs got merged into cranelift/codegen/src/machinst/abi.rs, so your changes just need to be applied to that file instead.

Otherwise, I think this looks like it does what you say it should do. @cfallin, now that it's implemented as a pseudo-instruction, what do you think?

Thanks for the reminder! I didn't realize this had a conflict.

There is an additional question that I'd like to ask for opinions. After this PR (as it is) we have two flags, enable_probestack and probestack_strategy. Should we merge those flags by adding a disabled arm to probestack_strategy?

Looks great to me! I think this is the right approach. I didn't look closely at the emission code but the sequence in the comments seems reasonable, as does the unrolled-vs-looping optimization.
