[BoundsSafety] Unbreak several codegen tests
This commit (and its corresponding merge commit) broke several codegen tests. ``` commit 4b59b95 Merge: c5ca745 c37b254 Author: git apple-llvm automerger <am@git-apple-llvm> Date: Fri May 2 23:22:29 2025 -0700 Merge commit 'c37b2549ff01' from llvm.org/main into next commit c37b254 error: cannot run gpg: No such file or directory Author: Yingwei Zheng <[email protected]> Date: Fri May 2 05:21:59 2025 +0800 Revert "[InstSimplify] Fold getelementptr inbounds null, idx -> null (llvm#130742)" (llvm#138168) Revert llvm#130742 for now to avoid breaking glibc failures until the workaround patches are landed. ``` This commit re-generates the failing codegen tests. rdar://150697626
