[PATCH] D157499: [IR] Add noreadafterunwind attribute

[Arthur Eubanks via Phabricator via llvm-commits]

aeubanks added a comment.

needs a verifier check that the attribute isn't a return value attribute

a follow up change will infer this for `sret` args in `inferattrs`?

is this intended to be derivable for args of internal/private functions or mostly just for `sret`/something the frontend can add?

what changes would need to be made to sink the store in https://gcc.godbolt.org/z/hnddhTqWa ?
