[PATCH] D147982: Account for PATCHABLE instrs in Branch Relaxation

[Jessica Paquette via Phabricator via llvm-commits]

paquette added a comment.

I think it's okay to keep all of this in one patch.

I put the MIR test through Compiler Explorer to see what is outlined (and removed some of the stuff that isn't necessary in MIR):

It looks like this, without this patch, does outline something with `PATCHABLE_FUNCTION_EXIT`, but we don't get any outlining behaviour for `PATCHABLE_FUNCTION_ENTRY`.

Would it be possible to add a case where `PATCHABLE_FUNCTION_ENTRY` is outlined without this patch?
