⚠️⚠️⚠️ Buildbot failure⚠️⚠️⚠️Hi! The buildbotaarch64 Debian Clang LTO + PGO 3.x has failed when building commit52cc4af. What do you need to do: - Don't panic.
- Checkthe buildbot page in the devguide if you don't know what the buildbots are or how they work.
- Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/1084/builds/2489) and take a look at the build logs.
- Check if the failure is related to this commit (52cc4af) or if it is a false positive.
- If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

gen_closeneeds to know whether aRESUMEfollows aYIELD_VALUEwhich is at except-depth 1, for an important optimization. Currently the compiler stores this information in the oparg ofYIELD_VALUE, which requiresgen_closeto peek into the bytecode (which is unsafe in the debugger). This PR puts this information in the oparg of theRESUME, and removes the oparg ofYIELD_VALUE. The result is simpler and safer code in gen_close.It also removes an anomaly in the bytecode definitions, where we needed to add a meaningless assertion to make the code generator understand that YIELD_VALUE has an oparg even though it doesn't use it.
